Ansh Chatterjee never intended to unleash ancient forces upon Mumbai. But fate, as always, ignored the fine print.







One night, he’s just a teen doomscrolling conspiracy forums over Maggi noodles. By dawn, he is neck-deep in a techno-mystical quest following clues left by an ancient Indian civilisation that may have cracked quantum entanglement back when Dwarka still existed.







With a sarcastic hacker , a fringe theorist , and a meditative dog who may or may not understand Sanskrit, Ansh races to answer two chilling





-Did ancient India unlock a technology that could bend physics? And consciousness?





-And who’s been burying that truth for 3,000 years?







Because the force that ended that world? It’s waking up.





And now, it knows his name.





This isn’t just about the past. It’s about a future scripted centuries ago – by minds powerful enough to rewrite reality.





And Ansh?





He’s the glitch they didn’t see coming.





ABOUT THE AUTHOR





Sheetal and Samiran are two-thirds of the award-winning 3 Techies Banter podcast, where sharp insights meet fearless speculation, and irreverence is always welcome.





Sheetal is a seasoned qualitative researcher with a knack for uncovering the stories people don't even realise they're telling. Whether decoding patterns in human behaviour or spotting meaning in the mundane, Sheetal brings deep curiosity and sharp insight to everything she does. And somewhere between Mahim’s cosmic mysteries and the chaos of Shivaji Park’s coffee shops, she always finds the truth.





Samiran is a technologist who playfully delves into history and obscure trivia no one cares about. Constantly battling "thaasophobia" (a fear of boredom), he is currently exploring the possibility that the Bandra Worli Sea Link might be more than just a bridge – perhaps even a wormhole to another dimension.





Together, they've devoted countless hours theorising about ancient civilisations and contemplating whether Mumbai's pigeons are covert operatives or simply avid fans of vada pav. This book marks their first literary adventure, where bygone India encounters tech conspiracies amidst Mumbai's dynamic and unpredictable backdrop.

In the bustling chaos of modern Mumbai, where twenty million stories unfold daily in spaces designed for two hundred thousand, Sheetal Choksi and Samiran Ghosh have crafted something extraordinary. Thuldrun.Sunya isn't just another urban fantasy—it's a mind-bending exploration of what happens when ancient Indian wisdom collides with cutting-edge technology, all wrapped in the delightfully chaotic embrace of Mumbai's streets.

The story follows eighteen-year-old Ansh Chatterjee, a perfectly ordinary Mumbai teenager whose life takes a spectacular turn from mundane to mystical overnight. What begins as late-night conspiracy theory browsing over Maggi noodles evolves into a reality-warping quest that challenges everything we think we know about India's ancient past.

A Protagonist Worth Following

Ansh emerges as a refreshingly authentic young adult character—neither the chosen one of typical fantasy nor the brooding anti-hero of contemporary fiction. He's genuinely curious, technologically savvy, and carries that particular brand of Mumbai wit that makes him instantly relatable. His journey from skeptical teenager to reluctant keeper of cosmic secrets feels organic, driven by intellectual curiosity rather than destiny.

The supporting cast brings remarkable depth to the narrative. Anya, Ansh's mother, balances fierce maternal protection with her own secretive work at the mysterious Enza corporation. Uncle Rotoro provides both comic relief and genuine wisdom as the conspiracy theorist podcaster whose wild theories might not be so wild after all. Each character feels genuinely rooted in Mumbai's cultural fabric, speaking and behaving like real people you might encounter at a Dadar station or Shivaji Park.

Mumbai as the Ultimate Character

What sets Thuldrun.Sunya apart is its masterful use of Mumbai as more than mere setting—the city becomes a living, breathing character. The authors demonstrate intimate knowledge of the metropolis, weaving references from Banganga Tank to Marine Drive, from the chaos of local trains to the mystical energy of ancient temples.

The narrative captures Mumbai's essence perfectly: a city where the sacred and profane dance daily, where ancient mysteries hide beneath modern facades. When the authors describe Dadar's traffic jams as "a couple of road-rage-driven homicides waiting to happen," or note that "maybe the real spirit of Mumbai was the restraint all residents showed by not committing acts of genocide while waiting impatiently at traffic lights," they capture the city's paradoxical nature with humor and affection.

The Thuldrun Concept: Ancient Tech Meets Modern Mystery

The central premise proves both audacious and compelling. Thuldrun represents an ancient Indian civilization that achieved technological advancement rivaling or surpassing modern capabilities—not through alien intervention or magic, but through advanced understanding of physics and mathematics. The authors ground this fantastical concept in real scientific principles, from thorium-based energy to quantum entanglement theories.

The integration of the mathematical zero (śūnya) as both philosophical concept and cosmic force demonstrates the authors' sophisticated approach to blending mythology with science. Rather than dismissing ancient knowledge as primitive, they suggest our ancestors might have understood fundamental truths about reality that we're only now rediscovering.

Technical Writing Prowess

The authors display impressive command over technical details, from cybersecurity concepts to quantum physics principles. Ansh's hacking sequences feel authentic, incorporating real tools like HashCat and proper encryption terminology without overwhelming non-technical readers. The balance between technical accuracy and narrative accessibility showcases the authors' expertise across multiple domains.

The dream sequences and interdimensional travel maintain logical consistency within the established rules of the fictional universe. The "Void" functions as both mysterious cosmic force and practical plot device, allowing characters to navigate between timelines and realities while maintaining story coherence.

Humor and Heart

Perhaps most impressively, the authors maintain a consistent tone of irreverent humor without undermining the story's emotional weight. The narrative voice captures that particular Mumbai sensibility—capable of finding humor in chaos while remaining deeply connected to family and community values.

The relationship dynamics between Ansh, his parents, and friends ring true to contemporary Indian family structures, complete with the loving interference, unspoken expectations, and fierce loyalty that characterize modern urban Indian families.

Masterful Technical Integration

The authors demonstrate exceptional skill in weaving complex quantum physics explanations seamlessly into the narrative flow. The technical exposition enhances rather than interrupts the story, providing readers with genuine scientific insights that enrich the reading experience.

The multiple timeline sequences showcase conceptual brilliance, creating an intricate narrative structure that perfectly serves the story's themes about the interconnectedness of past, present, and future. This sophisticated storytelling approach rewards attentive readers with deeper layers of meaning.

Literary Merit and Cultural Significance

Thuldrun.Sunya makes important contributions to contemporary Indian speculative fiction. It challenges Western-centric narratives that position ancient civilizations as primitive while celebrating India's actual historical achievements in mathematics, astronomy, and philosophy.

The novel successfully bridges the gap between traditional storytelling and modern genre fiction, creating something that feels distinctly Indian while remaining universally accessible. The authors avoid the trap of exoticizing their own culture, instead presenting Mumbai and Indian traditions as naturally integral to the story's fabric.

Themes That Resonate

The novel explores several profound themes through its adventure narrative:

• The persistence of ancient wisdom in modern contexts
• Family loyalty tested by secrets and supernatural circumstances
• The responsibility that comes with knowledge and power
• Technology as both liberation and potential destruction
• The thin boundaries between reality and possibility

Writing Style and Voice

Choksi and Ghosh demonstrate remarkable narrative control, shifting seamlessly between action sequences, technical exposition, emotional moments, and comedic relief. Their voice feels authentically youthful without being juvenile, technically informed without being pretentious.

The chapter titles alone ("Fairly Uncomplicated Mathematics Enroute Banganga," "Worlds Are Colliding, Collapsing, And We're All Just Vibing") showcase the authors' playful approach to serious subjects.
Target Audience and Appeal

While marketed as young adult fiction, Thuldrun.Sunya offers sufficient complexity and depth to engage adult readers. Science fiction enthusiasts will appreciate the technical rigor, while fantasy readers will enjoy the mystical elements and ancient civilization mysteries.

The novel particularly appeals to readers interested in:

• Urban fantasy with authentic cultural grounding
• Scientific speculation based on real physics principles
• Coming-of-age stories with genuine stakes
• Indian literature that doesn't exoticize its own culture

Final Verdict

Thuldrun.Sunya announces the arrival of talented new voices in Indian speculative fiction. Choksi and Ghosh have created something genuinely original—a story that celebrates both India's ancient achievements and its contemporary vitality while delivering genuine thrills and emotional resonance.

The novel succeeds as adventure story, family drama, and philosophical exploration of humanity's relationship with knowledge and power. It offers hope for a more inclusive future of science fiction, one where all cultures contribute their wisdom to our understanding of what it means to be human in an infinite universe.

For readers seeking intelligent entertainment that respects both scientific rigor and mythological significance, Thuldrun.Sunya provides exactly what its title promises: a journey into the cosmic void pregnant with infinite possibilities, guided by characters you'll genuinely care about through a city you'll want to visit again and again.

This marks an auspicious debut from authors clearly destined for continued success in the speculative fiction landscape. The infinity symbol (∞) in their title hints at more adventures to come—and after experiencing Thuldrun, readers will eagerly anticipate whatever impossible realities Choksi and Ghosh dream up next.

Reviewed By: Neel Preet

This incredibly-remarkable title, “Thuldrun.Sunya” is one of those rare sci-fi meets mythology crossovers that does not just flirt with ambition, rather it goes all in, headfirst. Interestingly, author Sheetal Choksi and author Samiran Ghosh construct a narrative that feels like a quantum-infused roller coaster through Mumbai’s underbelly, ancient India’s forgotten brilliance, and the messy brilliance of modern Gen Z chaos. At its core stands Ansh Chatterjee, a perfectly ordinary teenager whose biggest nightly battle should have been finishing his Maggi before it gets soggy. Instead, he accidentally triggers a sequence of events that resurrect a techno-mystical past no one was supposed to remember, especially not him. Besides, the manner in which both the authors had carried out the task of storytelling in their book is captivating enough to make the readers quench for more with every turn of the page, and this is something that actually makes this title reading worthy!

Author Sheetal Choksi and author Samiran Ghosh are two-thirds of the award-winning 3 Techies Banter podcast, where sharp insights meet fearless speculation, and irreverence is always welcome. Sheetal is a seasoned qualitative researcher with a knack for uncovering the stories people don't even realise they're telling. Whether decoding patterns in human behaviour or spotting meaning in the mundane, Sheetal brings deep curiosity and sharp insight to everything she does. And somewhere between Mahim’s cosmic mysteries and the chaos of Shivaji Park’s coffee shops, she always finds the truth. Samiran is a technologist who playfully delves into history and obscure trivia no one cares about. Constantly battling “thaasophobia” (a fear of boredom), he is currently exploring the possibility that the Bandra Worli Sea Link might be more than just a bridge – perhaps even a wormhole to another dimension. Together, they've devoted countless hours theorising about ancient civilisations and contemplating whether Mumbai's pigeons are covert operatives or simply avid fans of vada pav. This book, “Thuldrun.Sunya” marks their first literary adventure, where bygone India encounters tech conspiracies amidst Mumbai’s dynamic and unpredictable backdrop.

The title, “Thuldrun.Sunya” opens with a tone that is deceptively light, cleverly lacing Ansh’s late-night doomscrolling and conspiratorial curiosity with a sense of impending dread. What begins as harmless browsing on fringe forums quickly spirals into a chase involving cryptic symbols, subterranean archives and clues hinting that an ancient Indian civilisation may have unlocked technologies capable of bending the physics we treat as gospel. The authors walk a tightrope, here by blending mythology, quantum mechanics and speculative futurism and yet the pacing stays tight, the narrative structured, and the stakes escalate with precision. The result is a world that feels engineered with care — familiar enough to be recognisable, but thrillingly altered by the possibility that history hid far more than it revealed. Moreover, the supporting cast is a masterstroke of tonal balance. The sarcastic hacker, the eccentric theorist with one foot in genius and the other in absurdity and the meditative dog whose philosophical reactions raise the question of whether he truly understands Sanskrit, as each character injects vitality into the story!

On top of that their interplay ensures that the narrative never sinks under the weight of its heavier, metaphysical threads. When the plot pivots from humour to existential dread, the transition feels deserved, not abrupt. There is a smooth coupling between wit and wonder, tension and levity, making the book accessible without ever condescending to the reader’s intelligence. As the story unfolds, what becomes most compelling is its interrogation of forgotten knowledge and the forces determined to keep it forgotten. The authors build a conspiracy that spans millennia, where the downfall of an ancient civilisation was not just tragedy but deliberate orchestration. The force that extinguished that world is awakening, its awareness sharp enough to identify Ansh as the unexpected variable in a centuries-old equation. This adds a simmering suspense throughout the book, as every revelation feels like an echo from a past that refuses to stay buried, pushing the narrative towards a future that feels both unavoidable and terrifying.

One of the Notable Strengths of this novel, “Thuldrun.Sunya” lies in its ability to remain compulsively readable. The prose is sharp, modern and unabashedly Gen Z in tone not as gimmick, but as an authentic extension of Ansh’s worldview. Even in moments when the narrative dives deep into quantum entanglement, consciousness theory, or esoteric mythology, the storytelling never loses pace. The humour acts as a pressure valve, the suspense holds steady, and the mysteries land with satisfying weight. It’s a rare blend of intelligence and irreverence that makes the novel appealing to both hardcore sci-fi fans and readers who simply enjoy clever mythological thrillers!

Another remarkable aspect is how the book resists binaries. It doesn’t pit science against spirituality but presents them as two expressions of the same universal curiosity. The ancient Indian civilisation that forms the core of the mystery is treated with intellectual respect, not mystical exaggeration. Quantum mechanics and mythology converse fluently, finding common ground in questions of consciousness and reality manipulation. This marriage of scientific wonder with cultural depth is what gives “Thuldrun.Sunya” its unique resonance. It becomes a meditation on how ancient wisdom and modern science, when stripped to their essence, both seek the same truth — the blueprint of existence.

Now, upon reaching the final part of the review, i.e. the Book Verdict, we can conclude that a title like “Thuldrun.Sunya” is for sure a reading worthy title. The book deserves a chance by the readers as it thrives on its originality. It refuses to mimic Western sci-fi structures, choosing instead to anchor its speculative arc in Indian history and cultural logic systems. The fusion is seamless as Myth becomes science; science becomes myth; and the boundary between them collapses in ways that feel both innovative and deeply rooted. The final impression is one of exuberant creativity — a narrative that dares to imagine an ancient world far more advanced and enigmatic than textbooks suggest, while posing urgent questions about the technologies and beliefs shaping our future. Well, if you are searching for a book that fires on every cylinder — suspense, intellect, humour, mythology and big-scale speculative drama, then this title is a MUST READ one for you!

I loved how Thuldrun didn’t feel like it was trying too hard. It’s just a cool, weird story with a lot of imagination. The idea that ancient India had technology beyond our understanding? That really hooked me. But it’s not written like a textbook or mythology lesson, it’s fast-paced and full of small, funny moments too. The dialogue felt real, and I liked how the characters weren’t perfect heroes. They mess up, panic, and still keep going. It felt like an adventure I could picture happening right here, right now. That’s what made it fun!!!

• BOOK REVIEW: 𝐓𝐇𝐔𝐋𝐃𝐑𝐔𝐍.𝐒𝐔𝐍𝐘𝐀
• AUTHOR: 𝐒𝐇𝐄𝐄𝐓𝐀𝐋 𝐂𝐇𝐎𝐊𝐒𝐈 & 𝐒𝐀𝐌𝐈𝐑𝐀𝐍 𝐆𝐇𝐎𝐒𝐇
• GENRE: 𝐘𝐎𝐔𝐍𝐆 𝐀𝐃𝐔𝐋𝐓/ 𝐔𝐑𝐁𝐀𝐍 𝐅𝐀𝐍𝐓𝐀𝐒𝐘/ 𝐒𝐏𝐄𝐂𝐔𝐋𝐀𝐓𝐈𝐕𝐄 𝐅𝐈𝐂𝐓𝐈𝐎𝐍

🂱 It is my first time reading something that combines philosophy, ancient Indian mythology, and cosmology - THULDRUN.SUNYA plays with modern science and technology. The characters are funny and well plotted. It is interesting how the whole story doesn't play hard to believe it but it all went smooth.

🂱 The plot is set up on a question: WHAT IF ANCIENT INDIAN CIVILIZATION HAD DEVELOPED POWERFUL SCIENTIFIC OR METAPHORICAL TECHS HIDDEN ACROSS THOUSANDS OF YEARS, AWAITING TO REDISCOVER ITSELF?

🂱 Ansh Chatterjee, a teenager with utmost curiosity and tech interest is living his mundane life in Mumbai. He is extremely normal. A 18 or 19 years old boy eats noodles, browses forums and makes himself a sort of internet hacker freak. He is fairly regular in his routine life. Everything is normal. Right?

🂱 Something is calling him. An ancient conspiracy - 3000 years old algorithm. A message appeared “Ansh. I have been waiting for you”. But who? And why? And where? It comes with its own effects. Everything links with him - like this is beyond this massacre situation.
This is where Thuldrun comes - an algorithm is tied to ancient civilization that is advanced in science and modern technologies. It feels like everything matters here - SUNYA or emptiness, there's something empty but also everything is up to date. SUNYA is not just about absence but it is presented as potential, a philosophical and cosmic force. But there is something that is beyond any control. But what's next? What will happen to Ansh?

🂱 The past forces are awakened now and manipulate modern day technologies. Now Ansh has the power to choose - whether to engage with that to uncover the mystery or stay back and leave this to deal with human kind? That went interesting - conflicts between morality or personal choices or ancient metaphysics vs modern techs?

🂱 Did I feel goosebumps? Are you kidding? Ofcourse. With this vibrant writing, I felt MUMBAI alive. I felt I have seen the geography, history, decaying and aging of the city at the same time. The old architecture felt safe and usual. It serves as a tie to the present.

🂱 This book makes its readers create their own imaginative world where everything seems filled with knowledge - mainly the author's potentiality to explore science and techs with history and myth cuts the barriers. It felt like forcibly opening a new arena where we can both enjoy our limits. With every tension and revelation, this book left with a live portrait of how not to erase these feelings from our heart.

🂱 I'm not kidding if I say this book is mandatory for all the readers to explore a new phase. ✨

Imagine if your late-night Reddit browsing suddenly tore a hole in reality—welcome to Ansh Chatterjee's world. Choksi and Ghosh have engineered something brilliant here: a techno-mystical thriller that treats ancient Indian civilization not as mystical fantasy fodder, but as legitimately advanced science we've simply forgotten.

What hooked me immediately was the authenticity of Ansh's hacker sequences. These aren't Hollywood-style "I'm in!" moments—they're genuine cybersecurity procedures, complete with HashCat attacks and proper encryption protocols. When Ansh cracks the DragonCrypt challenge, every technical detail rings true, from GPU overheating to padding-oracle vulnerabilities.

But the real genius lies in how seamlessly the authors merge this technical precision with Mumbai's chaotic energy. Ansh isn't some isolated tech prodigy; he's embedded in a living city where Uncle Rotoro records conspiracy podcasts, mothers practice yoga to YouTube videos, and family dinners revolve around Gulzar poetry recitals. The Mumbai references aren't tourist attractions—they're lived experiences, from Dadar station's crush-loads to Banganga Tank's hidden mysteries.

The Thuldrun concept itself is fascinating: what if ancient India had mastered thorium-based energy and quantum mechanics? Rather than dismissing this as fantasy, the authors ground it in real physics principles. The mathematical concept of śūnya (zero) becomes both philosophical foundation and cosmic force—a beautiful marriage of India's actual scientific contributions with speculative possibilities.

Ansh's character development feels organic rather than forced. His progression from conspiracy-curious teenager to reality-bending navigator happens through genuine intellectual curiosity, not mystical destiny. When he discovers his parents' secretive work at Enza corporation, the family dynamics ring absolutely true to contemporary Indian households.

This is urban fantasy done right: scientifically literate, culturally authentic, and genuinely thrilling.

Are you ready for an enigmatic physics-defying ride?
Wondering why, because the book Thuldrun.Sunya by Sheetal Choksi and Samiran Ghosh offers you an exhilarating tour of a world where merchants trade in ideas and philosophises, humans ride dragons and objects float defying gravity.The main protagonist Ansh Chatterjee, the lover of conspiracies always felt his world wasn't stiched together as it was supposed to be.Since 2024, he experienced things that completely altered his life.While decoding cryptic codes around a conspiracy theory, he stumbled upon a world whose existence can be traced back to ancient Indian civilization in Dwarka, India.
During this journey we come across his other companions Riya, his best friend, Galileo, the philosophical dog, Rahul, VJ and UG Rotoro.

The addictive concoction of conspiracy theories, secrets, quantum mechanics and mythology against the backdrop of beautiful chaotic Mumbai kept me glued to the book till the last word.
As a science fiction lover, I couldn't get enough of the mind boggling experience it offered, the mere thought of a futuristic physics defying world supported by ancient knowledge gave me goosebumps.I would love to recommend this book to all the readers.

“It wasn’t discovery that changed him. It was what he refused to become after discovering.”

Sometimes our greed grows so deep that it blinds us—we chase desires so fiercely that we forget how essential they might be for someone else.

The book “Thuldrun.Sunya” by Sheetal Choksi and Samiran Ghosh begins with Ansh, a Maggi-loving, curiosity-driven student who spends his time exploring wild conspiracies online—until one day, he stumbles upon something that pulls him into a world he never imagined.

With help from Mira, his classmate, and teammates Niyati and Kabir, Ansh embarks on a quest to uncover secrets hidden within the vibrant yet shadowy layers of Mumbai.

The story beautifully explores themes of power, responsibility, and rediscovering purpose—reminding us that knowing something isn’t what defines you, but what you choose to do with that knowledge.

A gripping and thought-provoking read! Waiting eagerly for the next installment to unravel the mysteries that still remain.

Thuldrun starts in a Mumbai bedroom with a boy who feels like most of us - curious, a little lost, and just trying to get through the day. But then, things change. He finds strange signs, meets unusual people, and slowly gets pulled into something ancient.

The story mixes science, history, and mystery, but keeps it real. It’s easy to follow. The writing is sharp and funny. I loved the dog! Haha.

A smart, weird, and thoughtful ride through time, cities, and ideas. It feels personal, like the author really wanted to say something but let you figure it out yourself.

As a Mumbaikar, reading about conspiracy theories unfolding in our city felt incredibly relatable 😋

The authors clearly know Mumbai - from the late-night Maggi sessions to the chaotic energy that defines our city. Ansh's character feels like someone you'd meet in any college here, just doomscrolling and trying to make sense of the world. The idea that ancient forces are stirring right here in Mumbai, where we rush past history every day on our way to work, is both thrilling and oddly believable. The references to actual Mumbai locations make this feel authentically local while the stakes kept me turning pages. 👌

Thuldrun starts as a teen's late-night internet rabbit hole evolves into an epic quest that reframes everything we thought we knew about ancient India. The supporting cast, especially the Sanskrit-speaking dog adds a delightful absurdity that I really enjoyed 🐕💖

The idea that advanced civilizations might have unlocked reality-altering technologies challenges Western-centric views of technological progress. Mumbai's chaotic energy perfectly mirrors the story's escalating tension.


A beatiful fusion of archaeology, quantum mechanics, and pure imagination that leaves readers questioning historical assumptions.

What is real? What is unreal? How would you chalk up a difference between the two? A dream that plays in front of your eyelids while asleep is a figment of your imagination but the brains that dreams is as real as the bones that cage it. Thuldrun Shunya is a tour de force, a saga that starts in Maharashtra and ventures into a hidden world developed beyond imagination. It's a flight of fantasy that comes hurtling out of the paper, gripping you in its papery claws, not letting you go for a long long time.

Ansh Chatterjee , a troubled soul, grappling with ADHD, anxiety and stress is waiting for his Caltech results. But more than that, there is something that's on his mind, constantly gnawing, etching it's place in his skull. He has come across a vastly developed world Thuldrun. It's a best kept secret: did ancient India discover how to bend physics according to their will?
But this discovery has put Ansh in immense danger. He can feel a menacing black shadow following him. His mental peace has been shredded. His mother is breathing down his neck. And an ancient force might have become his enemy. But why? Well you have to read the book. I won't tell you everything here.

Such stories, where charcters set out on a journey to achieve something when odds are stacked against them, are my favourite. And here Ansh is on a life-bending odyssey. The world of Thuldrun is majestic. Here merchants don't just trade in wares but also in ideas and philosophies. Sculptures defy gravity. Chariots race across the sky, chased by dragons.

The author duo of Ghosh and Choksi have built up emotion, drama and mystery and throw their characters into the mix. The reader can't help but build a bridge of empathy with the lives of these people. An emotional cord is immediately hooked and it continues until the last page is turned over. The world of Ansh, his parents, Uncle Rotoro, Galileo feels not made up but organic. A special mention here is to rotund Uncle Rotoro, 'with frame carrying the kind of comforting heft that suggested he never turned down a second helping of aloo poshto'.

Although the story is set in Mumbai, the characters have their roots in Bengal. I loved the peppering of Bangla words and landmarks in the story: Peter Cat, Daaknaam, paanch phoron, lucchi, ilish macher jhol, kosha mangsho, shukto, lau ghonto, ghugni and many more. The story is also strewn with heavy jargon related to IT world that brings a certain authenticity since our main character is a kind of computer geek.

The authors take their time setting up the story. Instead of jumping straight, they set up the atmospherics and weaves the story tightly around the characters that will matter as the story progresses. They have written about young adult angst with ease, dexterity and a delicate sensitivity that makes you feel for these characters.
Have a look: "Born and raised in the heart of Mumbai, Ansh Chatterjee seemed to have it all: comfort, supportive parents and opportunity. But there was something that never felt quite right. Since childhood, he had carried a sense of wrongness, a feeling that his world wasn't stitched together as it was supposed to be. He couldn't tell anyone; how could he when he lacked the words for it? He knew what people thought of him: an intelligent, easy-going young man with every opportunity at his feet. So that was the mask he wore."

These nuances and detailing of the characters however don't affect the pace of the story. Ghosh and Choksi keep their characters crisp without letting the layering affect the story. The storytelling is engaging and the writing style skilful. The characters feel real and full bodied, not lifeless and cardboardish. The reader feels helpless as there is only one goal in the present and now: to finish the book. Everything else comes later.

I had a great time reading it.

Thuldrun.Sünya - A Relic , A Rift, And A Really Bad Day

Authors - Sheetal Choksi And Samiran Ghosh

I could have never imagined the city I was born in, in such a fascinating way as depicted in this story. It left me awestruck.

‘Mumbai,’ a chaotic and endlessly alive city, turns into something else entirely in this story, it becomes a breathing, ever-shifting being made of secrets, memory, and ambition. Even a one-eyed stray dog wandering through Dadar’s cracked pavements feels strangely meaningful, like a quiet messenger from somewhere beyond. There are such subtle and haunting details that the story begins to blur the line between the ordinary and the extraordinary.

Ansh Chatterjee, a brilliant yet restless young man, feels an unsettling wrongness about his world, as if reality itself is slightly out of tune. When his nights begin to fill with strange “glitches,” time loops, and impossible dreams of a floating city called Thuldrun, he realizes that something far larger than himself is unfolding. What begins as curiosity grows into a journey that connects his family, his city, and perhaps all of human history.

Each chapter unfolds like a revelation and Through Ansh’s eyes, Mumbai transforms into a layered realm of possibilities , a place where the ancient and futuristic coexist, where every street corner might hide the remains of a forgotten civilization. As he delves deeper, guided sometimes by cryptic symbols and sometimes just by instinct (and the mysterious reappearances of that same stray dog), the familiar world of Dadar, Parel, and Malabar Hill begins to thrum with hidden meaning.

Running alongside Ansh’s unraveling reality is the story of his parents, Anya and Kanishk, both are scientists who work with a shadowy corporation, Enza, that touches the same forces that haunt their son’s dreams. Their lives, built on ambition and secrecy, mirror the story’s larger question, humanity’s fierce need to hold sway over creation itself.

Between quantum ideas and ancient crafts, the story draws powerful links between myth and science, reminding us that both come from the same human hunger to understand the unknown.

The book moves seamlessly between its worlds, the glass towers of Enza and the luminous streets of Tula-Dvī-Rūņa , without ever losing emotional depth. Beneath all the chaos and mystery lies a deeply human tale: a son searching for truth, parents bound by guilt and love, and a family caught in the echoes of a collapsing reality.

Thuldrun.Sünya is Book One of the ♾️ series by Sheetal Choksi and Samiran Ghosh, and it’s a striking start to a saga that feels ready to spill beyond the boundaries of time, myth, and imagination.

Sheetal Choksi and Samiran Ghosh have created something truly special with 'Thuldrun.Sünya'. They have turned Mumbai into a world that feels both real and dreamlike, mixing science, legend, and emotion in a way that feels raw and alive. The symbolic details and cosmic touches shine through each page, showing how deeply they understand both the city and the mystery of life itself.

“They switched up to whatsapp as this unkown stranger could read,hear and see them on their machines .Ansh glanced back up at his monitor and saw that the screen was black. there was just a message , a message ment for him.”
“ Found it yet? Thuldrun, It is so close to you ,It waches you you watch it, we’re watching you “

THULDRUN
Authors- Sheetal Choksi & Samiran Ghosh

I Loved, the way each chapter has a symbol in header which kept the visual hunger of knowing what this chapter carry ,no doubt that this book is outcome of both our writers who devoted their numerours hours for ancient civilizations , a perfect blend of a techie and a researcher which comes in the for of thuldrun sunya.

though i feel this book sometime use complex jargon but overall it is a good read

The story features Ansh, who races against time and mystery to answer two chilling questions. Along the way are a sarcastic hacker, a fringe theorist, and a meditative dog (who may or may not understand Sanskrit). The plot dips into science fiction, secrecy, metaphysics, and hidden layers of reality.

at first this book ask super concentration from me honestly my interest started building after chapter 1 but does that mean you can skip that chapter A COMPLETE NO because that set up the plot on which the book goes forward… and do not skip the Epilouge

Blend of the unusual & hackers and conspiracies gives the narrative a fun twist you expect sci-fi thriller tropes, but there’s also whimsy and spiritual undertones.
Mystery & suspense The chilling questions that set off the plot draw you in immediately. You keep wondering what’s behind all this?
Characters with edge The hacker, the fringe theorist each feels eccentric but necessary in building the world.
Philosophical depth-The title “Sunya” (emptiness, void) suggests deeper themes what is nothingness? What lies beyond perception? The novel teases those layers.
You Should Read It

Because it’s not just a plain sci-fi thriller. It’s a puzzle with spiritual shards something that makes you pause. Want a story that makes you question the known, blend tech + mysticism, and still keeps you guessing? This is it.

At times, Thuldrun.Sunya felt like a doorway to a parallel reality just when I thought I knew where it was heading, it twisted again. The characters and their motivations kept me invested. The dog that might understand Sanskrit? That line hit me who says spiritual and strange can’t coexist?

I can’t spoil the big reveal, but let me tell you the “questions” you begin with are not the same by the end. The unknown becomes more intense.

👉 Do you like stories that mix science + mysticism and never let you rest?
so if i am able to convince you enough do give it a read.

"It wasn’t that he’d abandoned reason, no. He saw science as a shapeshifter, evolving, sometimes sprouting a few more tentacles than expected. His dream world seemed to exist within the challenge. His instincts told him it all began with one word, the word that had echoed in his mind for such a long time, that he’d forgotten where or how he’d heard it or even knew the word: Thuldrun. The cursed land. The promised land. The one thing that shouldn’t exist. The other world."

____________________


What if the myths we grew up listening to were not just stories, but coded truths about a science far beyond our understanding? That’s the thought that pulled me into Thuldrun.Sunya by Samiran Ghosh and Sheetal Choksi.

I started reading this book because I enjoy sci-fi, whether in movies or novels, they open doors to imaginative possibilities and let me travel across strange landscapes without leaving my room. This story did exactly that.

At its heart is Ansh Chatterjee, a teenager from Mumbai who is a curious lad having great passion at learning who suddenly finds himself tangled in mysteries that connect ancient Indian civilisation with futuristic concepts like quantum entanglement. He’s browsing conspiracy forums, chasing clues that question the very fabric of reality that dates thousands of years! But what is Thuldrun or rather where is it and what is there?

As the story progresses with a good of balances modern-day Mumbai like the traffic, everyday chaos it also captures the hidden worlds of old temples, relics, and forgotten knowledge.

So, this keeps the story realistic yet at each point we find something to explore!

Ansh is not your typical hero but you know like us funny, and often confused, which made him more relatable. Like he is our friend and we walk besides him in his quest. And he has an unusual team comprising of a hacker, theorist, and even a dog but despite its heavy themes, humorous elements are there to keep it enough light for a joyful read.

The book raises big questions about whether ancient India might have held scientific knowledge powerful enough to shape the future. It mixes mythology, science, and a bit of drama in a way that feels both familiar and fresh. For me, it was like standing on the edge of two worlds at once.

If you are into scific that actually holds your hand and walks you through steps built upon mythology and some fantasy then this book is gonna be a mystic ride into a mind boggling time travel for sure! Go for it. Thuldrun.Sunya is available on Amazon.

What if ancient myths were not just bedtime stories but cryptic accounts of advanced science lost in time? Welcome you all to this World of "Thuldrun.Shunya" by Sheetal Choksi and Samiran Ghosh. It's is an astonishingly esoteric fusion of mythology, science, fantasy and thriller.

The saga will take you on an exhilarating exploration of tantalising possibility which blends Indian mythology, cutting-edge quantum theory and everyday hustle of the city of Mumbai into a thrilling adventure.

The story revolves around a teenager, Ansh Chatterjee whose life takes a surreal turn when he unknowingly unlocks an ancient mystery about a civilization which understood quantum stuff millennia ago.

And what starts as a regular scrolling over noodles fantastically turns into a quest which also involves a sarcastic hacker, a fringe theorist and a meditative dog fluent in Sanskrit. And together they chase something which blur the lines between science and mythology!

The character building in this book is next level. The authors has put before us a genuine  youngster Ansh with whom we will be falling in love from the very beginning. Ansh is not like typical overpowered hero unlike most in this genre. 

Ansh and other supporting character's awkward sarcasm, genuine confusion and quiet determination give the story a realistic flow. The setting and space make over make it more vibrant and exciting. 

The kind of themes which this book explores needs seasoned readers to digest technical stuff yet the book can be a best challenger for beginners to explore something new and  exciting. I personally enjoyed reading this book.

And i will highly recommend it to everyone who has a crave for a thought provoking adventure into history, science and mythology with exciting characters. Do grab your copy from Amazon 😊

There's something deeply moving about watching a young person discover that everything they thought they knew about the world—and their family—is built on carefully constructed lies. Thuldrun.Sunya captures this universal coming-of-age experience through Ansh's journey, but amplifies it with cosmic stakes that somehow never overshadow the intimate human moments.

Sheetal Choksi and Samiran Ghosh understand that the best fantasy grows from emotional truth. Ansh's relationship with his mother Anya feels achingly real: the love, the distrust, the way secrets create distance even when everyone's trying to protect each other. When Anya practices her breathing exercises to "keep the screaming out," we feel her desperation as both mother and woman trapped by circumstances beyond her control.

The authors excel at finding humor in chaos without diminishing genuine emotion. Uncle Rotoro's podcast obsessions and his beloved Fiat Millecento provide comic relief, but never at the expense of his genuine concern for Ansh's safety. Even Galileo, the rescued dog, becomes more than comic relief—he's family stability in an increasingly unstable world.

What makes this story special is how it honors family bonds even as it explores cosmic mysteries. The Chatterjee family's love for each other anchors the reality-bending elements. When Ansh finally reunites with his father Kanishk in the Void, the emotional payoff feels earned because we've witnessed their relationship's complexity throughout the narrative.

Mumbai itself becomes a character that embraces contradiction—where ancient temples coexist with modern technology, where street vendors serve customers through floods, where twenty million people somehow make impossible logistics work through sheer determination and love.

The ending promises more adventures, but what lingers is the emotional resonance of a family choosing trust over secrets, connection over safety.

Every now and then, a book comes along that takes a familiar city, a few everyday characters, and then yanks you straight into a world you didn’t see coming. Thuldrun.Shunya does exactly that.

It begins simply enough,Ansh Chatterjee, a teenager in Mumbai, wasting time on conspiracy forums with a bowl of Maggi. He’s curious, sarcastic, a little lost basically the kind of kid you’ve probably met. But by the next morning, he’s neck-deep in a chase that connects ancient Indian myths, forgotten temples, and cutting-edge ideas about consciousness and quantum physics.

What I loved most is how the story balances its scale. On one hand, it’s playful: there’s a hacker with too much attitude, a theorist with more ideas than common sense, and yes,a dog that may or may not understand Sanskrit. On the other, it’s ambitious: asking questions about whether ancient India held knowledge powerful enough to rewrite reality itself.

The city of Mumbai is almost another character in the book,crowded trains, chaotic streets, Shivaji Park,everyday places that suddenly feel like doorways to something hidden. The writing is sharp and funny, which makes even the heavy science and mythology easy to follow.

What makes Ansh stand out as a protagonist is that he’s not a typical “chosen one.” He’s awkward, skeptical, often confused, but that’s exactly what makes him relatable. You cheer for him not because he’s perfect, but because he feels real.

In the end, Thuldrun.Shunya isn’t just a sci-fi thriller or a mythology reimagined. It’s a story about curiosity, about asking what if? and then running full-speed into the answer, noodles forgotten.

If you enjoy books that mix the familiar with the fantastical,where humour sits comfortably next to big, reality-bending ideas,this one is worth picking up.

You know that feeling when you start a book and within a few pages, you just get this grin on your face because you can tell you're in for something special? That was me with Thuldrun.Sunya. I picked it up because the cover was cool and the blurb mentioned a dog that might understand Sanskrit, which is honestly a selling point I never knew I needed.

This book is a total trip. It follows Ansh, this regular kid in Mumbai who’s just minding his own business, probably stressing about school or something, when he accidentally stumbles into this massive, ancient mystery. The way the authors describe it feels so real—one minute you’re scrolling on your phone, the next you’re questioning the very fabric of reality. His crew is hilarious. There's this sarcastic hacker who I absolutely loved, and a conspiracy theorist who you can't help but root for. And the dog? The dog totally steals every scene it's in. They all just clicked for me, like a group of friends I'd want to get into trouble with.

What really got me was how the story blends these huge, crazy ideas with the everyday chaos of Mumbai. It’s not some generic, shiny sci-fi city; it’s packed with life, from the street food vendors to the old temples hiding secrets. The authors weave in all this wild stuff about ancient tech and quantum physics, but it never feels confusing or preachy. It just feels exciting, like you're figuring it all out alongside Ansh.

I blew through this book in a couple of days. It’s the kind of story that makes you look up from the page and realize you’ve been completely lost in another world. It’s fun, it’s clever, and it has so much heart. If you’re even remotely into stories that mix science, history, and a great adventure with characters you’ll love, you have to give this one a shot. I’m already hoping there’s a sequel.

Every conspiracy theory is a joke… until this book makes it real!

♾INSIGHT: The book revolves around 18-year-old Ansh Chatterjee, who has always felt out of sync in this so-called normal world. When he chances upon a conspiracy theory on Reddit that steers his life in a new direction, replete with nightmares, visions, the blurring boundaries between illusion & reality, & a lost civilisation called Thuldrun, Ansh embarks on the quest of a lifetime to protect everything he holds dear. But is it already too late?

♾REVIEW: An ambitious, genre-bending novel that grips you from the very first line, & keeps you on the edge of your seat the entire time. I found the book to be an absolute page-turner, with crisp, powerful narration, and well-developed characters. There are sufficient twists & turns throughout, and the pacing is spot on. The book is a blend of mythology, fantasy & science fiction, thus appealing to all those who enjoy the speculative genre. That being said, it can be a bit difficult to follow the story initially if you are a beginner-level reader in the genre, especially the technological jargon related to hacking. Regardless of that, the novel is an engrossing & compelling read that will leave you wanting more by the end.

♾STRENGTH: 1. The writing style is eloquent but lucid, in keeping with the broader themes.
2. A very engrossing read with even pacing & ample twists & turns.
3. Rounded & realistic characters.
4. Set in Mumbai, I loved how the book captures the pulse of the city.
5. The subtle tones of sarcasm & humour was refreshing.
6. Immersive world-building.

♾WEAKNESS: 1. The technological jargon may be initially off-putting to the uninitiated.

♾TARGET READERS : Ages 17 & up

♾GENRE: Science fiction

♾RATING: 4.4/5

Ansh Chatterjee’s story is the kind of book that grabs you with its wild premise and refuses to let go, even when you want to roll your eyes a little. On one hand, it’s absolutely entertaining late-night Maggi, doomscrolling conspiracies, and suddenly you’re thrown into a world of ancient Indian civilisations tinkering with quantum entanglement. On the other, it occasionally tries to do too much, leaving you slightly dizzy with all the science-mythology mashups.

I loved how grounded Ansh feels at the start. He’s awkward, sarcastic, and far from your typical “chosen one” which makes his tumble into this techno-mystical quest feel believable. His banter with the hacker character is hilarious, and the theorist reminded me of those uncles at weddings who think they’ve cracked the universe. And the dog? Pure joy. Honestly, I’d read an entire spinoff just from the dog’s perspective.

Where the book stumbles for me is pacing. Some sections dive so deep into theories and ancient tech that I found myself skimming, wishing we’d get back to the characters. At times, it feels like the story can’t decide if it wants to thrill you with action or impress you with knowledge and in trying to do both, a few scenes lose their punch.

But despite these bumps, it’s hard not to ignore the ambition. The book feels fresh in the way it blends myth and science, and it asks questions that linger long after you’re done. Did ancient India know more than we give it credit for? And if they did, what would we do with that knowledge now?

Mumbai isn’t just a setting in Thuldrun. It’s alive, chaotic, and cosmic all at once✨ Choksi and Ghosh take you from Dadar station to the Void itself, blending the city’s pulse with interdimensional secrets, thorium science, and ancient Indian wisdom.

At the heart of it is Ansh Chatterjee is a Maggi slurping teenager whose late night conspiracy dives turn into a mind-bending journey across timelines. Unlike most fantasy heroes, he feels strikingly real, awkward, curious, and reluctantly heroic.

What Works:

-> Mumbai written as a character which is full of contradictions, humor, and energy.
-> Bold blend of science, mythology, and philosophy without losing heart.
-> A protagonist who feels authentically Mumbai teenager rather than a stock “chosen one.”
-> No pandering, no over-explaining, instead just deeply Indian storytelling.

Where It Falters:

-> A dense, slow-burn opening that demands your full focus.
->Heavy tech jargon that may overwhelm non-tech readers.
->The narrative occasionally juggles too many big themes at once.

✅Read if you love ambitious speculative fiction that’s original, rooted in Indian culture, and unafraid to tackle big ideas.

❌Skip if you prefer light, breezy fantasy with quick pacing and minimal science.

This isn’t just a fantasy novel, it’s a cultural statement disguised as an adventure, reminding us that India’s ancient wisdom might hold keys to future possibilities.

Ansh wakes up every day plagued by strange nightmares involving a magnificent city, Thuldrun. He is convinced that this city is real and that a portal exists somewhere in Maharashtra, leading to a hidden world that is shrouded in secrecy for a reason. It is up to him and his dysfunctional group to figure out how and why they are catching glimpses of this parallel realm. As they navigate the dangers of being silenced, the group takes on the challenge of discovering this beautiful yet terrifying world, where the true power of the Gods is revealed.

"Thuldrun.Shunya" is an urban fantasy with a dash of mythology and sci-fi written. It is set in the heart of the city of Mumbai. The story traverses iconic locations such as Shivaji Park and the legacy of The Bombay Scottish School, Mahim, to the vibrant suburbs of Maharashtra. The author’s engaging and relatable writing helps readers believe in the existence of a hidden world behind familiar, everyday places.

All the characters are well-developed, including Ansh's parents, who add an interesting dynamic to the story. Riya, Ansh's childhood buddy and partner-in-crime has played her part equally well.

If you want to experience the Bambaiyya vibe within a contemporary sci-fi framework, be sure to pick up this debut novel by the author duo. This marks the beginning of an infinite series.

Book Review : Thuldrun Sunya by Sheetal Choksi and Samiran Ghosh

Thuldrun.Shunya is one of those books that hooks you with a “what if” and doesn’t let go. What if your dreams are more than just dreams, and instead, visions of another world? That’s exactly what happens to Ansh, an average boy from Mumbai who finds himself a player in an ancient intrigue, along with a collection of quirky, not-so-principled friends, discovering the rich shafts of mythology, science fiction, and the energy of the city around him.
What I loved most about the narrative is how real it is, even as it pushes into bizarre territory–ancient tech, quantum theories, and even a dog that speaks Sanskrit! Ansh is also a delightful narrator. He transports readers through his sarcasm, confusion, and determination, which allows readers to cheer for him along the way. The group feels real too, and even with the twisty nature of the narrative, there are moments of humour that balance the heavy ideas as they go along.
Mumbai itself is almost a character here, grounding the narrative where Shivaji Park, and the frenetic aspects of daily life in the city's chaos make an underlying world feel real.
If you like fast-paced adventure stories that mix-up a cocktail of history, science, and imagination with a strong sense of space, Thuldrun.Shunya is a fun read.

🪷What a ride! It is the perfect blend of mythology and sci-fi with a Gen Z spin, and believe me , I was literally unable to stop reading this book till the end comes. It is based on the adventures of an ordinary teenager, Ansh Chatterjee, who accidentally finds himself in a place of ancient mysteries, lost technologies, and interstellar threats that seem to be both surreal and terrifyingly real.

🪷The most unique thing about this book is the way in which it smoothly intertwines with Indian history, Indian mythology, and quantum physics without ever getting out of proper pace. One minute you are laughing at the snapshot sarcasm of Ansh about Maggi noodles, and the other moment you are experiencing the adventure quest of Ansh finding clues Left by  an ancient civilisation which can be proof of Dwaraka's existence . There is also the supporting characters, a rogue-hacker, a lunatic theorist, and even an oddly philosophizing dog, which introduces so much vitality and humour that the narrative never becomes too serious even when the more philosophical issues are addressed.

🪷It is clever, exciting, and unlike anything I've ever read. It is the ideal choice when you need a book that will engage the mythological thriller and speculative sci-fi crowds.

"Thuldrun Book One Of ♾️" by Samiran Ghosh and Sheetal Choksi is one book that takes you places and keeps your mind on the loop with all the glithes going on in the book. What exactly is Thuldrun? How was it related to the protagonist and what history does it have with his parents? Is it the reason his bestfriends parents split up or was it a place she sought refuge when she needed a place for escape? what is reality and what exactly is the truth? Whom to trust and who not to?

The story line is exceedingly mind gripping for me and the author has wooven around the glitches and blackouts including the pull into a universe which cannot be crossed by humans all too real.

This book is a wholesome experience of a city with secrets to hold, secrets that date back to ancient history, a curious teen who is eager to find out the glitches she goes through, a dangerous hacker who gets hold of data but would it be used for good or evil? And a mediative dog who may or may not understand Sanskrit. A blend of Physchics, History and a whole lot of Technology, a book which glitches you definitely would not want to miss out.

Buckle up, folks! Ansh Chatterjee's wild ride is a turbo-charged mix of ancient mysticism, quantum weirdness, and Mumbai street smarts that'll keep you flipping pages till the wee hours.

From Maggi-fueled midnight conspiracy binges to chasing clues left by Dwarka's ancient wizards, Ansh's techno-mystical quest is equal parts desi desi and cosmic crazy. His crew – a hacker with attitude, a theorist on the fringe, and a dog who might just be a Sanskrit scholar – is as unlikely as it is awesome.

This isn't just another ancient-tech-meets-modern-world story. It's a full-throttle thriller asking: what if ancient India cracked the code to bending physics and consciousness itself? And who'd want to bury that truth for millennia?

The writing's kinetic, the stakes are sky-high, and Ansh – that glitch in the ancient script – is a protagonist you'll root for. Get ready for a future that's actually the past catching up, and Mumbai's very own hero trying to outrun the awakening forces of... well, Dwarka.

Sci-fi fantasy meets ancient Indian mythology👆

👉About the book:
Ansh Chatterjee never intended to unleash ancient forces upon Mumbai. But fate, as always, ignored the fine print.

One night, he’s just a teen doomscrolling conspiracy forums over Maggi noodles. By dawn, he is neck-deep in a techno-mystical quest following clues left by an ancient Indian civilisation that may have cracked quantum entanglement back when Dwarka still existed.

With a sarcastic hacker, a fringe theorist, and a meditative dog who may or may not understand Sanskrit, Ansh races to answer two chilling questions:

-Did ancient India unlock a technology that could bend physics? And consciousness?

-And who’s been burying that truth for 3,000 years?

Because the force that ended that world? It’s waking up.

And now, it knows his name.

This isn’t just about the past. It’s about a future scripted centuries ago – by minds powerful enough to rewrite reality.

And Ansh? He's the glitch they didn’t see coming.

👉Mind-bending. Fast-paced. Fantasy Thriller.

👉When are you picking it up?

While growing I was always fascinated to read any article about Dwarka the ancient submerged city in Gujarat. It's about how ancient technology establish the link to the future generations and how it can be recovered. 


Thuldrun, book one by Sheetal Choksi and Samiran Ghosh is one such take on the unfolding the mysteries around Dwarka and finding an answer in such twisted tale. It is built around the story where worlds are going to end but just us humans are busy in our own worlds. But the solution which could help us save is lost in the city of Dwarka and its ancient technology. 


The story line initially builds tension around it and the characters are introduced nicely. The writing style could have been better with not extending the story through the lines but rather could have been kept short, on point and crisp. This might have engaged reader more and keep them resonated with what is going to happen next.

📚 Thuldrun starts like any normal day - Ansh is just a teenager, chilling in Mumbai. But then, small strange things begin to happen, and before he knows it, he's pulled into a mystery way bigger than him. It’s not just about science or history - it’s about something ancient that’s still alive in the world today.

📚 What I liked most was how the book mixed modern life with ancient secrets. One moment you’re reading about traffic and snacks, and the next you’re thinking about old temples and lost knowledge. It all fits together like a puzzle that slowly makes sense.

📚 The story also makes you feel like maybe the past is not as far away as we think. It made me curious about old Indian stories and how they might connect to real science. Thuldrun makes your brain light up in new ways. I enjoyed.

BLOWN AWAY. This book is what happens when someone with serious writing chops decides to explore the "what if" of ancient Indian scientific achievements. The Authors
have created something genuinely original here - part Dan Brown thriller, part hard science fiction, part coming-of-age story, all wrapped up in a deeply researched exploration of India's forgotten scientific legacy.

The Mumbai setting is perfect - a city where ancient and ultra-modern collide daily, making it the ideal backdrop for this story.

The supporting characters each bring something unique to the table, and that dog... I won't spoil it, but be prepared for some unexpected wisdom delivered with perfect comedic timing. 🙌😂

Highly recommending Thuldrun for anyone who enjoys intelligent speculative fiction with heart.
