The Tartarus Conspiracy: Seven Thrilling Days Before Dystopia

by William J. Oxfield

Seven days. Three continents. One ancient secret that was never supposed to surface.
Investigative journalist Amanda VanderBilt receives a single phone call. She has seven days before something catastrophic is set in motion — something her grandfather died trying to prevent, and her father was destroyed trying to expose.
What she uncovers is older than any government. Older than any religion.
Hidden in the Dead Sea Scrolls. Encoded in the Book of Enoch. Buried beneath thirty years of classified military research at a facility that officially does not exist.
An ancient order called the Tagma Lumis has been protecting this secret for millennia. A second faction — operating inside the highest levels of government and intelligence — intends to weaponise it.
And the countdown that both factions have been waiting for is almost over.

THE TARTARUS CONSPIRACY spans Washington D.C., Isfahan Iran, and Jaunpur India across seven relentless days. Three protagonists — a journalist, a baker, and a soldier — each holding one piece of a puzzle none of them fully understands, converging on a truth that will rewrite everything humanity thinks it knows about its own history.
This is a global conspiracy thriller built on real ancient texts. The Watchers. The Nephilim. The 70-generation sentence of Tartarus. The imprisoned beings whose release Revelation 9 describes in precise operational detail.
The mythology is not invented. The countdown is not a metaphor.

About the author

William J. Oxfield is a Dutch author of conspiracy thrillers built on real ancient texts: the Book of Enoch, the Dead Sea Scrolls, the Watcher narrative of Second Temple Judaism, and the cross-cultural mythology that every major civilization preserves in fragments.

His debut novel, The Tartarus Conspiracy, reached #1 in the Netherlands (Christian Mystery & Suspense) and won the Readers' Favorite 5-Star International Book Award. It has been compared to Dan Brown, H.P. Lovecraft, Robert Ludlum, Dean Koontz, Matthew Reilly, Joel Rosenberg, Amir Tsarfati, Brad Thor, Jack Carr, Tom Clancy, and Frank Peretti. It is a global conspiracy thriller spanning Washington D.C., Isfahan Iran, and Jaunpur India across seven days before dystopia.

The research behind the series is not invented. Over twelve years, Oxfield observed something that academic scholarship tends to miss because it treats religious traditions in isolation: every major civilization on earth -- Hebrew, Sumerian, Greek, Norse, Hindu, Islamic, Incan -- preserves the same fragmented memory of the same ancient events. The descent of divine beings. The corruption of humanity. A catastrophic flood. The imprisonment of the guilty parties. A sentence with a fixed duration. And a release that the oldest surviving texts describe in precise detail.

The Book of Enoch is the most complete account of what all these traditions are pointing at. The VanderBilt Trilogy is built on that foundation.

Oxfield spent 27 years as VP Operations at a global logistics company. The Tartarus Conspiracy was written alongside a full corporate career, across twelve years, by someone who had never written a novel before and had to learn everything from scratch. His editor Mark Legatt's instruction stayed with him throughout: "We are in the business of entertainment. The only thing that matters is that you deliver this story as sharply as you can."

He is a pianist, a church board member, and lives in the Netherlands with his family.

✨The Tartarus Conspiracy: Seven Thrilling Days Before Dystopia✨

This book is a beast of a dystopian thriller, intricate, sprawling, and absolutely relentless. If you enjoy stories that blend genres, The Tartarus Conspiracy offers a strong narrative that lies between a military-grade geopolitical thriller and a deep dive into cosmic horror and ancient myth.

The main story unfolds over a seven-day countdown, giving the book a stressful, ticking clock feeling. Journalist Amanda VanderBilt makes a great protagonist. She is dedicated, professional, and troubled, fighting not just for the truth but also against an existential threat that is erasing the boundaries of reality.

What really impressed me was the wide scope and world-building. Oxfield skillfully contrasts high-tech, ominous portals under Groom Lake, Nevada, with the rich religious symbolism in cities like Varanasi. This creates a striking contrast between cold, sterile government facilities and ancient places full of faith and legend. The ensemble cast—especially the stories featuring the seer Ebrahim and military operatives like Kian and Ivani—makes the global conspiracy feel frighteningly real and well-organized.

If you enjoy fast-paced action, well-researched conspiracies (the military and intelligence details are excellent), and a completely immersive reading experience, pick this up. It's a cleverly crafted page-turner that will leave you eager for more from this complex, dystopian universe.

It is a mix of mystery, science, and ancient legends. Amanda VanderBilt, a sharp investigative journalist, gets a call that sets off seven intense days of nonstop danger. The plot bounces around the world — temples, labs, secret bases — and every place feels vivid and exciting. I loved how the book blends global politics with eerie, myth-based threats. The characters each bring something unique, and their teamwork keeps the story interesting. The ancient-entities-awakening angle is spooky in the best way. Overall it was a great read - a great story to read.

Fascinating mix and an enjoyable read

I found this book to be a fascinating mix of thriller, mythology, and religion that holds together really well. The story moves at a good pace, jumping from Washington to India and beyond, as journalist Amanda VanderBilt digs into a conspiracy involving ancient myths, secret experiments, and prophecy. A very enjoyable read.

[Sneha · Rating 5 out of 5]

If you’ve been craving a thriller that makes your pulse race and your brain hurt (in the best way), The Tartarus Conspiracy is it. Ancient myths, secret experiments, and a conspiracy that could literally rewrite reality, yeah, we’re not in your average “missing person” story anymore.

Amanda VanderBilt, an investigative journalist with serious guts, gets one mysterious phone call and ends up diving headfirst into a rabbit hole of buried truths, missing family, and world-shattering secrets.

This book moves fast. One minute you’re in Washington’s power corridors, the next you’re decoding sigils in India or chasing prophecies in Iran. William throws you into a perfect storm of science, religion, and mythology, and it’s pure, unfiltered chaos, the fun kind.

What makes it even cooler? It’s not just about secret organizations and creepy ancient beings, it’s about family, faith, and the cost of truth.

Amanda’s determination gives the story heart amidst all the high-stakes madness. You’ll want to grab popcorn and a notebook for theories.

[H.S. Harding · Rating 4 out of 5]

I really enjoyed the core concept of The Tartarus Conspiracy. It's packed with high-stakes action, a richly complex and believable world brimming with mystery and danger, and a gripping blend ofhigh-level government conspiracies, ancient prophecies, and near-future mad-scientist schemes. The plot drives everything forward with relentless momentum, making it a thoroughly engaging read from start to finish.
The only thing holding it back from a full five stars is the occasional melodramatic dialogue and lines that pulled an eye-roll from me. With so much inherent drama, tension, and excitement already in play, those over-the-top moments felt unnecessary and occasionally distracted from the story's strengths.
Overall, this is a solid, ambitious thriller that's well worth your time. Four strong stars—I'm glad I picked it up!

[Maeve Tra · Rating 4 out of 5]

3.5/5 rounded up because I think this book deserved the recognition

The Tartarus Conspiracy is one of those books that you can’t help but pull an all-nighter for. From the opening pages, Amanda VanderBilt’s race to uncover her family’s buried secrets launches into a globe-spanning conspiracy involving ancient myth, secret military experiments, religious prophecy, and unsettling Watchers mythology.

The seven-day countdown gives the story strong momentum, and the short chapters make it easy to keep going. The scope is massive, varying from continents, faiths, to hidden facilities, and cryptic research notes. I was overwhelmed, but in a good way.

That said, the book needs some more editing. In an attempt to create tension and urgency, there were a lot of incomplete or run-on sentences. Some of the dialogues felt melodramatic or cheesy. While the pacing is good, it felt suffocating at times. I think the book would benefit from a little ‘quiet’ time, some breathing room per se.

Overall, The Tartarus Conspiracy is a bold, high-concept thriller that delivers suspense, scale, and plenty of late-night page-turning. It may not be perfectly polished, but its ambition and intensity make it a memorable ride.


Thank you to NetGalley and BookBuzz for providing a digital ARC in exchange for an honest review.

Here supernatural, religious philosophy and government conspiracy converge to produce a fast paced thriller that doesn’t disappoint.

It has engaging characters, it’s fast moving, there are plot twists here, gripping action there and the writing is full of hooks and breadcrumbs that will have you turning page after page.

Can’t wait for the next one.

[Leanne · Rating 4 out of 5]

The Tartarus Conspiracy is a bold, high‑stakes thriller that sweeps you from the familiar into the uncanny with a pace that never lets up. It blends ancient myth, global politics, and apocalyptic tension into a story that feels both cinematic and unsettlingly intimate, anchored by Amanda VanderBilt — a journalist who’s spent her life living in the shadow of the secrets that destroyed her family.

Amanda’s journey begins with a single cryptic phone call, but it quickly spirals into something far larger than she ever imagined. The novel moves through encrypted notebooks, abandoned research, and military experiments with a propulsive energy, each revelation tightening the net around a conspiracy that stretches across continents and centuries. The sense of scale is enormous, yet the emotional core remains grounded in Amanda’s determination to uncover the truth her father and grandfather died chasing.

The mythology threaded through the narrative — the Watchers, prophecies, celestial alignments — adds a rich, eerie texture without ever tipping into excess. Instead, it deepens the sense that something ancient is stirring beneath the surface of world events, and that the vanishing of people across the globe is no coincidence. The countdown structure, with only seven days before a catastrophic revelation, gives the story a taut, breathless momentum.

What makes the book especially compelling is how it balances its dystopian scope with the vulnerability of its protagonist. Amanda isn’t a chosen one; she’s a woman piecing together a legacy of loss, betrayal, and buried knowledge, and the weight of that history gives the thriller its emotional resonance.

A gripping, atmospheric race against time, The Tartarus Conspiracy delivers mystery, mythology, and geopolitical intrigue in a way that feels both expansive and deeply human. It’s the kind of story that keeps you turning pages long after you meant to stop.

My thanks to William J Oxfield, the publisher and netgalley for the ARC

[Sterling Vance · Rating 4 out of 5]

William J. Oxfield's The Tartarus Conspiracy throws readers into a genre-bending thriller that spans continents and centuries in a single breath. Opening with a blood moon rising over a secret underground laboratory beneath the Nevada desert, the novel wastes no time establishing its stakes: ancient orders, government cover-ups and forces that predate recorded history are all colliding in the present day.
At the centre of it all is Amanda VanderBilt, a sharp, battle-hardened investigative journalist whose estranged father's fall from grace turns out to be the first thread in a much larger tapestry. Her storyline pulls in Washington power players, Indian mysticism, Middle Eastern political unrest and biblical figures rendered as genuine threats, and Oxfield manages to keep these disparate strands moving without losing narrative momentum. The scope is genuinely impressive: few thrillers attempt this level of global, mythological reach, and fewer still pull it off without collapsing under their own weight.
The pacing favours tension over exposition. Scenes on the street, in morgues and in gaming cafés crackle with the kind of paranoid urgency that keeps pages turning, and the surveillance and chase sequences are especially well handled. Dialogue between characters like Amanda and Peter carries real chemistry, and the supporting cast, from grieving informants to morally compromised White House staffers, adds welcome texture to the conspiracy.
Where the book occasionally stumbles is in prose polish. A handful of small typographical slips and repeated stylistic tics surface here and there, minor enough not to derail the read but noticeable enough to mention. Readers who prefer a tighter, single-thread plot may also find the sheer number of moving parts, mythological, political and personal, a lot to track at once.
Still, for anyone who enjoys their thrillers big, mythic and unafraid of scale, this is a rewarding read. Oxfield has built something ambitious here, and it shows.
Recommended for fans of conspiracy thrillers with a supernatural edge.

Ik kreeg de kans van @william.j.oxfield om The Tartarus Conspiracy en The VanderBilt Deception: Part 1 te lezen, en ik was meteen verkocht.
Je bent gewaarschuwd ❕Dit zijn geen gewone thrillers. Je krijgt een mix van samenzweringen, geheime organisaties en een dreiging die alsmaar groter wordt.

In The Tartarus Conspiracy volg je Amanda VanderBilt, een onderzoeksjournaliste die op zoek gaat naar de waarheid achter een geheim dat al tientallen jaren verborgen wordt gehouden. Het verhaal zit vol spanning, korte hoofdstukken en verrassende wendingen. Soms zijn er veel personages en verhaallijnen waardoor je in het begin even moet doorzetten, maar het mysterie houdt je nieuwsgierig tot het einde.

The VanderBilt Deception: Part 1 gaat nog een stap verder. De gevolgen van wat in het eerste boek gebeurt, worden steeds duidelijker. De dreiging groeit, de actie neemt toe en de verschillende verhaallijnen vallen mooier in elkaar.

Wat ik de sterkste kant van Oxfield zijn pen vind, is de sfeer die hij kan creëren. Vanaf het begin voel je dat er iets iets groots op je af komt. De boeken lezen vlot, bouwen de spanning goed op en laten je voortdurend gissen naar wat er echt aan de hand is.

William J. Oxfield durft groots denken en risico’s nemen. Beide boeken zijn episch en filmisch. The Tartarus Conspiracy legt een sterke basis, terwijl The VanderBilt Deception: Part 1 toont dat de serie alleen maar beter wordt. Ook zijn schrijfstijl vind ik sterk gegroeid als ik beide boeken mag vergelijken. Waar het in het 1ste boek nog veel perspectieven biedt en veel achtergrondinformatie, zijn deze beter in elkaar verweven in boek 2. Je kan beide apart lezen, maar ik vond het wel beter en duidelijker als je de serie volgt. En pluspunt: ze zijn ook in het Engels te lezen!

[C.M. Adams · Rating 4 out of 5]

The Tartarus Conspiracy is an intense and immersive dystopian thriller that pulls you in fast and refuses to slow down. From the opening moments, the seven day countdown creates a constant sense of pressure that follows you through every chapter. This is not a casual read. It is the kind of book where you keep telling yourself just one more chapter and suddenly hours are gone. The blend of ancient myth, religious symbolism, government secrecy, and modern geopolitics feels ambitious, but it works remarkably well.

Amanda VanderBilt is a strong and compelling protagonist. As an investigative journalist, she feels grounded and believable, even as the story around her spirals into increasingly disturbing territory. Her personal connection to the mystery through her grandfather and father adds emotional weight to the conspiracy, making the stakes feel personal rather than abstract. You are not just racing against time to stop a catastrophe, you are watching someone dig through her own family’s buried past in search of truth.

The worldbuilding is one of the book’s biggest strengths. The contrast between sterile military facilities in places like Nevada and sacred, ancient locations in India and Iran gives the story a layered and unsettling atmosphere. The Watchers, and the way prophecy, science, and faith blur together, are genuinely creepy and thought provoking. Nothing feels thrown in for shock value alone.

If you enjoy fast paced thrillers in the vein of Dan Brown or Robert Ludlum, but with a darker, more dystopian edge, this book delivers. It is smart, relentless, and deeply immersive, and it leaves you thinking long after the final page.

YOU HAVE SEVEN DAYS TO COMPLETE THE ASSIGNMENT

Tartarus: the land of hell, evokes also Tartaria, the old name for what is now Russia east of the Urals. From Arlington to Langley, Through Islamist Persia and Communist Uttar Pradesh India and ranging all the way to Reykjavik, TARTARUS CONSPIRACY drives you on a forced march round the world linking ancient spiritual mysteries with contemporary geopolitics, with thrills driven by cosmic dread and ther relentless seven day countdown.

Amanda VanderBilt is a grounded, resourceful protagonist. Her grampa? Disappeared. Her dad? A discredited historian. The human heartbeat pulses through the action. Oxfield keeps the pressure on and drives the plot forward with tight engaging writing. Each chapter ends with a cliffhanger, compelling you to read the next one: this is what we call "a page turner".

World-building is it's best strength. Military precision in secret labs, underground bunker tunnel complexes aligned with spiritual vortices in Islamic Iran and the Communist Province of India. Symbols, prophecies, faith and ideas collide to shape the narrative as much as tech does. "The Watchers" fuse myth and modern biologenics.

Alongside Amanda, the seer Ebrahim and the operatives Kian and Ivani are distinct, capable, and essential to the web of conspiracies. Pacing never lets up.

Love conspiracy thrillers? Ready to face some deep philosophical questions? The Tartarus Conspiracy is yours. Smart, immersive, readable, with mystery, action, and myth to keep driven long after the seven day mission ends.

Five stars. Start digging—you won’t want to stop.

[Sonia Rompoti · Rating 5 out of 5]

As a writer myself, I went into this book thinking I’d read a couple of chapters before bed. Cute. Somewhere around 3 a.m., I was still whispering “just one more page”... and this is what happens when ancient myth, government secrecy, and religious prophecy all walk into a bar.. and then proceed to burn the place down.

Amanda is the kind of protagonist I follow into battle without asking questions. Every breadcrumb she uncovers made me sit up straighter, and every twist punched me right in the sleep schedule. Hidden research facilities, military experiments no one is supposed to know about, global disappearances, and a conspiracy that doesn’t politely stay in one country or one religion? Yeah. It’s that level. The pacing is ruthless (the bite-size of the chapters helps keep you hooked, trust me). The stakes keep getting higher. And Oxfield does not care about your comfort or your emotional stability while reading. At one point I had to turn off my Kindle, stare into the void, and then reopen it because I needed answers.

This isn’t a random dystopian thriller with a sprinkle of “maybe it’s supernatural.” This book commits. It digs into faith, history, and the terrifying idea that the truth has always been hiding right in front of us.

Don’t start it on a work night. Don’t think you’ll be reading “casually” — I warned you.

Five stars. Absolutely worth every lost hour of sleep.

William J. Oxfield delivers a phenomenal start to The VanderBilt Trilogy with The Tartarus Conspiracy: Seven Thrilling Days Before Dystopia. This book is an incredibly gripping dystopian thriller that seamlessly blends ancient myth, apocalyptic prophecy, and geopolitical intrigue into a relentless tale of survival. The story follows investigative journalist Amanda VanderBilt, who is plunged into a vast and dangerous conspiracy following a cryptic midnight phone call. She is forced to follow the perilous trail left by her discredited historian father and her grandfather, who vanished decades ago inside a top-secret underground facility.
I absolutely loved how the fast-paced narrative spans the globe, taking readers from the political corridors of Washington D.C. to sacred sites in India and Iran. As the tension mounts, the plot reveals chilling truths about exiled beings known as the Watchers awakening beneath the surface of world events. It is terrifying to read as celestial alignments converge, global religious prophecies blur together, and people across the globe begin to vanish without explanation.
With a ticking clock of only seven days before a cataclysmic revelation, the pacing is perfectly executed and kept me completely on the edge of my seat. Oxfield has crafted a dark, fascinating world full of encrypted notebooks, bloodstained sigils, and secret military experiments. This is an absolute must-read for thriller fans who enjoy a deep, mythic mystery!

[Andrew Levine · Rating 5 out of 5]

The Tartarus Conspiracy by William J. Oxford opens with a premise that instantly grabs attention: a secret society operating quietly behind global institutions, shaping events and pursuing power on a scale most people would never imagine. From the start, the novel pulls readers into a world where influence moves through shadow networks rather than public institutions.
Oxford handles the conspiracy-thriller formula with discipline. Instead of relying on nonstop action alone, he builds suspense through careful plotting and a steady stream of revelations. Each chapter peels back another layer of the mystery, gradually exposing the scope and ambition of the organization at the center of the story.
What elevates the novel is the author’s use of historical references and geopolitical themes. Those elements give the narrative a sense of authenticity that makes the conspiracy feel unsettlingly plausible. The characters are believable and grounded, which helps keep the story from drifting into implausibility as the stakes escalate.
The result is a fast-moving thriller that combines intrigue, history, and high-stakes tension.
Recommendation: Readers who enjoy conspiracy-driven political thrillers and stories about secret networks operating behind world events should find The Tartarus Conspiracy a compelling read.

[Khushi · Rating 5 out of 5]

It’s an atmospheric, slow-burn supernatural thriller that blends small-town mystery, folklore, and psychological tension into a gripping narrative. From the very first chapter, the book establishes a sense of unease strange disappearances, unexplained events, and a town weighed down by secrets that everyone seems afraid to speak aloud.
The world-building is one of the book’s biggest strengths. Oxfields feels fully alive: the forests, the old buildings, the quiet streets, and the ominous atmosphere create a setting that is both beautifully detailed and deeply unsettling. You can almost feel the chill in the air and hear the whispers beneath the silence.

The story follows a group of characters who slowly uncover the frightening truth behind the mysterious history of Oxfields. The character arcs are compelling each person carries their own fears, regrets, and motivations, and the author does a great job of showing how those inner conflicts influence their choices. As the supernatural elements intensify, the emotional stakes rise as well, making you root for the characters even more.

The book shines in its pacing: it doesn’t rush. Instead, it layers clues, tension, and revelations in a way that keeps you turning pages. The dialogue feels natural, the shifts between past and present blend smoothly, and the final portions deliver the kind of payoff that makes the buildup worth it.
What really elevates the story is the blend of psychological tension and supernatural mystery. It's not just about what lurks in the shadows it’s also about how fear shapes people, how secrets destroy communities, and how the past refuses to stay buried. The “Blood Moon” motif adds a symbolic and eerie undertone that ties everything together beautifully.
Overall, The Tartarus Co.: Oxfields Review is a haunting, immersive read perfect for anyone who loves atmospheric mystery, subtle horror, and stories where every detail matters. It’s the kind of book that stays with you long after you finish it, not because of jump scares, but because of its lingering, unsettling emotional depth

[Linda Sanchez · Rating 4 out of 5]

This book pulls you in from the opening chapter and never really lets go. The blend of ancient myth, global politics, and apocalyptic tension gives the story a huge scope, yet it still feels personal because you follow Amanda as she pieces together her family’s dark history. The pacing is sharp, and the sense of urgency grows with each chapter, making the seven-day countdown feel genuinely intense.

What stood out most to me was how seamlessly the story moves through different settings and layers of mystery. The cryptic research notes, strange symbols, and hidden facilities all create a feeling that something enormous is happening just beneath the surface of the world. The author does a great job balancing action with deeper questions about faith, history, and power.

Amanda is a strong lead who carries the emotional weight of the story. Her determination to uncover what happened to her family adds heart to the high-pressure plot. The global disappearances and the rise of the Watchers add a supernatural edge that feels both imaginative and unsettling.

If you enjoy thrillers that blend conspiracy, myth, and a race against time, this book delivers a gripping, memorable ride.

Investigative journalist Amanda VanderBilt receives a cryptic phone call unraveling her family's dark legacy: her grandfather vanished from a secret facility, her father died claiming dangerous truths. Following their trail through Washington D.C., India, and Iran, Amanda learns about the Watchers, ancient beings from religious myth. Exiled, the Watchers are awakening, and she has seven days to prevent all of reality being rewritten.

William J. Oxfield’s novel is an ambitious countdown thriller that reads like a head-on collision between Dan Brown and H.P. Lovecraft. What starts as a grounded journalistic hunt for family secrets rapidly descends into a chilling cosmic horror landscape. Ancient mythology transcends simple lore: it’s a terrifying biological reality. While the genre-bending might give purists whiplash, and the “kitchen sink” approach to mythology won’t please everyone, this blend of geopolitical intrigue and apocalyptic prophecy makes it an addictive, intelligent page-turner. Fans of Jim Butcher and Charles Stross will find a lot to like in “The Tartarus Conspiracy”.

A Dark Spiral Worth Following

Tartarus Conspiracy by William William J. Oxfield lands with a heavy, almost suffocating intensity—the kind of book that makes you pause after the first chapter because you can already feel the pressure building. It’s not just dark; it’s deliberately dark, the kind that lingers.

At the center is a protagonist who is less “heroic” than he is fractured. His bitterness isn’t loud or theatrical—it’s quiet, corrosive, and it shapes every decision he makes. That internal erosion becomes the true engine of the story; the conspiracy around him matters, but it’s his inability to outrun himself that gives the book its sting.

The prose is precise and often atmospheric, with a pacing that leans toward a slow burn—not sluggish, but intentional. You can feel the author tightening the screws one turn at a time, trusting the reader to sit with tension rather than sprint through it.

I’d recommend this book if you prefer character volatility over clean resolutions, or psychological unease over rapid-fire twists. It’s a story that rewards patience and appetite for shadows.

[Tiffany Solter, PhD · Rating 5 out of 5]

The Tartarus Conspiracy hit me hard....and I mean that literally. I lost an entire night to this book, turning pages long after I should have been asleep, and I woke up still thinking about it. William J. Oxfield writes tension like a man who understands that real courage isn't the absence of fear, it's acting through it. This line stopped me cold: "He saw the same tension reflected in his team's expressions. Technical Sergeant Miller's jaw was clenched tight, his gloved hand resting near his M4, and even First Lieutenant Johnson, usually unflappable through countless nuclear security details, had a trace of fear in his eyes." That single image....command, discipline, and dread sitting side by side in the same room....captures something I've spent years trying to articulate in my own work: that authenticity is forged under pressure, not before it. Oxfield gets it, and he gets it better than I've managed to say it myself. Briggs is a phenomenal anchor for this story, and the conspiracy simmering beneath the surface had me racing toward answers. I need the next book immediately. Five stars, no hesitation.

[Jesus Rocha · Rating 5 out of 5]

“The Tartarus Conspiracy surprised me in the best way. It is a great debut from William Oxfield. From the opening chapters, William pulls you into a tense and atmospheric story that blends history, politics, and constant thrill without ever feeling heavy or confusing. I really enjoyed how the plot starts with a big bang right off the bat and is able to continue the high rhythm of thrill through out the rest of the book. The author clearly provides a tense timeline throughout the seven days that are covered in the story.
It reads like a blockbuster movie, with a very detailed narrative and high level details of multiple locations, religions and cultures.
The protagonists have strong character development; they had to overcome many obstacles that kept the reader on the edge while maintaining accuracy and feasibility on the plot.
If you like intelligent thrillers with conspiracies, a bit of historical flavor, and characters you can actually care about, The Tartar Conspiracy is definitely worth reading

Beware! Generational Trauma
This dystopian thriller holds your attention from the first cryptic phone call and until the final revelation. It’s a story that covers ancient myth, geopolitical tension, and apocalyptic prophecy into a single, breathless countdown - seven days in which reality itself hangs in the balance.
At the centre of the novel is Amanda VanderBilt, an investigative journalist whose grandfather vanished inside a classified facility and her father was destroyed for uncovering truths the didn’t want exposed. When Amanda stepped into their shadowed trail, she didn’t realise that she was stepping into a legacy of danger.
The conspiracy she uncovers is vast and unnerving - encrypted notebooks, blood‑marked sigils, military experiments, and political corridors of influence on a global scope. As people begin to vanish, the supernatural and geopolitical threads fuse into a single, chilling realization that something old is waking, and humanity is running out of time. This is an ideal read for thos who love myth, danger, and secrets buried in history.

[Jessy Carlisle · Rating 4 out of 5]

I'm glad this book stated it's fictitious on the copyright page. I never would have known otherwise. There's a lot of religiously inspired fiction around these days so I appreciate this one's honesty. The usual theme of powerful people keeping things hidden plays out in an exciting way with the plot generally moving quickly. I like how Amanda is presented relatably as she tries to figure things out. The brevity of the final chapter made me wonder whether there may be a sequel, then I realised it's the first book in a trilogy. The little poem at the end leaves the reader with a final thought to ponder.

The formatting could be improved though. The copy I received for review lacked a Contents page. This could be a 5-star book were it not for that. Chapters started right after the prior one ended instead of taking a new page. The margins seemed a little unbalanced too but that could just be a display issue. Nonetheless, I like how it clearly states where each part is happening in bold centred text. The sans serif font used throughout is also easy to read.

[Andres · Rating 4 out of 5]

So the book is basically a dystopian thriller packed with ancient myths, scary conspiracies, and global drama. It kicks off with the hero (Amanda VanderBilt) getting a weird call, and boom,she’s thrown into this race across Washington, India, and Iran to stop a huge disaster in 7 days. Without spoiling too much, there’s a secret group called the ""Watchers"", and they might be more real than anyone ever thought. The way it mixes religion, science, and cosmic stuff makes your brain work overtime!

The author’s style is actually pretty easy for non-native speakers like me. I liked that the story jumped around locations and beliefs, it kept things interesting. The book has this one great moment where 1/ Amanda finds out something huge about her family and 2/ it actually changes how she sees the entire conspiracy.

That said, the pace is so fast that i sometimes got lost,on the downside, I wish some explanations were clearer.

This novel is densely written, packed with many different persons and their relationships over time. It was difficult at first to sort them out and keep up with the plot as a dozen characters are introduced rapidly in the first few pages. I had to make a few notes as I tried to hold an entire web before any single thread has been given enough length to stabilize. My brain was about to explode until I visualized each plot thread to be a spoke in a wheel revolving around the same center, echoing the same message.
No spoilers here, but a sinister reality underlies the rich plot tapestry with aliens and advanced technology standing in stark contrast to deities and layered mythology. All is revealed gradually. The fractal storyline takes place simultaneously in the US as well as remote and exotic settings connected by a long anticipated astronomical phenomenon.
One can't escape the pervading dark and somber threat of impending doom despite a biblical message of salvation.

I came across The Tartarus Conspiracy and the blurb caught my attention. The story moves quickly, mixing old legends, secret government experiments, and big risks. From the first page, I was hooked. Amanda’s search into her family’s past, while racing a seven-day deadline, made the story feel urgent and personal. The book is fast-paced, intense, and full of surprises. If you enjoy thrillers with clever mysteries, dark futuristic settings, and those moments when you realize the plot is much bigger than you thought, you should definitely give this one a try.


“In the end, the word is the most powerful form of creation given to mankind. To create, or erase.
To build, or destroy.
To love, or hate.
To worship, or idolize.
To heal, or fester.
To unite, or divide. Choose your words wisely. Oxfield”

I went into The Tartarus Conspiracy expecting a fast-paced thriller, and it quickly became something bigger and a lot stranger. From the opening, I was hooked by Amanda VanderBilt’s race to uncover her family’s buried secrets and a conspiracy that stretches across continents, faiths, and centuries. The seven-day countdown gives the story real urgency, and the globe-trotting plot feels cinematic, blending investigative journalism, secret military projects, and ancient myth in a way that kept me reading.

Not everything lands perfectly—some twists feel a little convenient, and the pacing can be almost too relentless—but the ambition is impressive. The Watchers mythology is unsettling and memorable, and Amanda is a compelling guide through the chaos. Overall, it’s a smart, complex thriller that rewards fans of Dan Brown–style conspiracies with a darker, more cosmic edge.

The Tartarus Conspiracy is a genuinely ambitious global thriller that earns its scope - jumping between a Washington DC journalist, a rogue Area 51 security chief, and a young woman in rural India whose village is fracturing around a false messiah, all converging on an ancient entity awakening after millennia. Oxfield handles the multi-faith dimension with more care than the genre usually manages, and the central mystery, rooted in a catastrophic event three decades earlier and tangled up in the protagonist's own bloodline, builds real momentum. If anything holds it back from five stars it's that the prose occasionally keeps the tension dial so high that individual scenes don't always get room to breathe - but that's a minor complaint about a debut that has genuine ambition and delivers on most of it. Four stars, and I'll be watching for what comes next.

The Tartarus Conspiracy opens with a cinematic punch—blood moons, secret labs, ancient entities, and a multi‑country cascade of ominous events. The pacing is quick, the atmosphere thick, and the global scope gives the story a sense of real urgency. Amanda’s investigative thread is especially engaging, blending personal trauma with high‑stakes mystery in a way that feels grounded despite the supernatural elements. The book clearly aims for a fusion of thriller, mythology, and conspiracy, and for the most part it delivers that energy.

Some sections feel dense with lore and rapid scene shifts, which may overwhelm readers who prefer slower, character‑driven buildup. But the ambition is undeniable, and the worldbuilding has a confident, cinematic quality. Overall, it’s a gripping, imaginative thriller with a strong sense of momentum and a clear voice behind it.
