Outlast. Outgrow. Outlive. In the ashes of Earth, evolution is the ultimate weapon.

The Earth will never be the same. Ravaged by climate destruction, nuclear devastation, and other cataclysmic events, the planet and its people continue to undergo radical changes to survive. A portion of humanity now lives aboard the city-size utopian space station Astrea—the lucky few. Most who fend for themselves on the Earth's surface have become Nomads: plant/fungus hybrids connected to the growing planetary mind of Earth. The few remaining human societies on Earth survive through incredible cunning, calculation, and courage.

Shira and Myriam, cybernetically enhanced warriors hailing from the now destroyed Matriarchy of Wintersvilla, travel across the world in search of a way to protect two human-like girls with seemingly impossible powers. As the women clash with giant mutated beasts and a diverse array of deadly flora, they are intercepted by a Huntress and Hunter—catastrophically lethal creations of the old world thought to have gone extinct over a decade earlier. While these characters' paths intersect in surprising and explosive ways, ancient powers lurk in the shadows, wielding god-like influence over their lives. Will Shira and Myriam be able to overcome their nightmarish adversaries, or will they succumb to the endless perils of the neoevolved Earth?

Dive into Mendel's Ladder, book one of this epic series, and prepare for an adrenaline-fueled journey set on a post-apocalyptic future Earth, brimming with high-stakes action, adventure, and mystery.

Mendel's Ladder
By E.S. Fein
This is rich in imagination, the plot, the many creatures or beings, and the world building. I got a bit confused at times, and it took a bit to understand what was happening. I think it's because this world is so vast in possibilities.
There is a city in the sky that is called Heaven because it's compared to the damaged earth. There are levels to the beings based on intelligence, power, and violence. There are warriors also. It's those that try to protect the world and certain others protect the girls. Difficult to follow at times. I plan to continue the series to see if the next book sheds more light.

I received the ebook of Mendel's Ladder via a reddit post by the author. This was a free ARC copy given to me in exchange for an honest review. Here it is:

Reading Mendels Ladder is like jumping onto a roller coaster that's just hurtling nonstop into a future that's both wild and deeply thought provoking. This is Earth in 2099, but it's like nothing you've seen before, with folks evolving into Nomads and flesh trees, these awesome human/plant mixtures. It's weird, it's crazy, but boy, is it cool.

The story revolves around a couple of hardcore ladies, Shira and Myriam, who are out to protect two unique human seeming (but not human?) girls. They've got this enigmatic Nomad as their ally, which just adds to the intrigue. And then you have the Hunter and Huntress, living weapons from a different time, both with their own agendas and stories that are as gripping as they are unnerving.

The prose in this book is something else. It is haunting yet compelling. There's a richness to his writing that had me hooked from page one. It reminded me of Dune in a lot of ways but with more action and a vibe that's very NOW.

What's really impressive is how Fein weaves all these narratives and characters together, creating a cohesive tale that's as profound as it is gripping. And the concept of the Nomads, along with Mendel's journal entries, really deepen the storyline, adding layers of philosophy that'll make you pause and think.

I've got to say, the characters in this book have been crafted with real care. They're flawed and relatable, and even though some aren't exactly likeable, you find yourself rooting for them anyway. The action sequences are jaw dropping and so intense, but it's the moments of emotion that really got to me.

Bottom line, Mendel's Ladder is a gripping read, packed with action, loaded with depth, and it'll have you thinking long after you've turned the last page. I'm stoked to see where the story goes next!

"Mendel's Ladder: A Grimdark Sci-Fi Epic" is the perfect read if you're looking for a quick-to-read, hardcore, original science fiction story.

We move 100 years into the future to find a very different Earth from the one we know. Earth is now a dystopian death world where humanity is on the verge of extinction due to the decisions and actions of a madman, Denis Mendel, who had his own vision for the evolution of the human species. A hunter and her huntress are looking to eliminate the last vestiges of humans on Earth. A couple of young girls are running for their lives, trying to reach a human sanctuary city before the hunter and huntress couple find them. The world is full of dangers such as mutants. A group of humans is living in space, overseeing the deadly evolution of Earth. All these stories will merge in this first episode of this epic sci-fi story.

It's a great work by the author, with an outstanding sense of world-building and imagination that has produced a quite enjoyable story. The only flaw I found in the story is that this is simply the first part of a great story, and we have to wait until the next release to know how the story keeps evolving.

I was offered a free advanced copy of this book. I assume some parts of the book might change before official publication. This review is my honest opinion.

E.S. Fein's novel, Mendel's Ladder, elevates the realms of scifi and dystopia into an intoxicating concoction of raw emotion, philosophical questioning, and adrenaline-fueled battles. Across an alien yet familiar Earth, Fein weaves layers upon layers of intricate lore and characters that are as profound as they are endearing.

The future Earth Fein paints is both fascinating, grim, yet somehow hopeful. With most of humanity transformed into Nomads, the world is a strange if not horrifying place.

Perhaps the most commendable facets of this tale is Fein's world building. From the nightmarish terrestrial expanse to the seemingly serene domain of Astrea, every detail feels meticulously crafted with a fevered imagination and methodical construction. His prose dances, drawing the reader into fast mpaced combat scenes and pausing gracefully during introspective moments that probe the very nature of existence.

For those familiar with Fein's earlier work, Points of Origin, Mendel's Ladder feels like a transcendental step forward, displaying a maturity in writing and a more profound understanding of the human experience. With fierce female protagonists, a melding of genres, and questions of morality taking center stage, this narrative is both a roller-coaster ride and a philosophical treatise seamlessly merged into one.

For readers yearning for a tapestry of emotions, intense unyielding action, and profound philosophical undertones, Mendel's Ladder is the literary feast you've been seeking. I already pre-ordered book 2. Thank you for the chance to read this incredible story before it achieves global recognition!

This is definitely one of the best books I've read in a long time!!!! It's fast-paced and action-packed. The world-building is excellent, and I'm totally invested into the characters' lives that the author is creatively weaving together. I'm glad E.S. Fein varies the narrators in each chapter since that allows us to dive deeper into multiple characters and plot lines. I'm hoping this trend will continue in book 2. I also like how there are journal entries before each chapter, and while we haven't technically met Denis Mendel, it's interesting to see how the journal is connecting the various plots together.

The worst part of the book is that I have to wait six months for the next volume to come out!!! I need to find out what happens to these characters and to this dystopian world!! I need to learn more about strong, loving Samuel who is truly devoted to his family; Shira and Myriam, two badass warriors who are fiercely loyal and protective of their loved ones; Rooli, a tree-like Nomad, who would clearly sacrifice herself to save the twin girls Aliana and Aurelia; Thompson, the Hunter, who has endured such horrifying abuse but is actively trying to change his programming; and so many more!

I highly recommend this book! I'm so glad it's a series!

A Triumph of World-Building, Philosophy, and Action

After leaving a comment on reddit for E. S. Fein's previous book Points of Origin on reddit, I was thrilled when the author reached out to me, asking if I would read an advanced reader copy of Mendel's Ladder. Having enjoyed Points of origin already, I dove into this new universe, and what a thrilling plunge it was!

From the outset, Mendel's Ladder stands out for the sheer uniqueness of its world-building. The dystopian Earth of the future is unlike anything I have ever encountered in literature. The concept of human-plant-fungus hybrids, called Nomads and Hybrid Nomads, connected to a vast mycelial network forming Earth's consciousness is both fascinating and entirely original. The depiction of diverse cultures, Mutants, Rovers, Hunters, deadly plantlife and the utopian space station Astrea adds layers of complexity that set the stage for a rich, textured experience.

The characters are the backbone of this incredible universe. Huge fan of Shira and her love for the girls. That was simply beautiful! Philosophically, this book dives into existential questions about evolution, survival, and morality. It doesn't shy away from engaging the reader in thought-provoking dilemmas, all while maintaining a pace that never lets up. The action sequences are nothing short of cinematic, filled with colossal battles and exciting.

But what truly sets Mendel's Ladder apart from other entries in the genre is its succesful blending of science fiction, fantasy, mystery, and even elements of litRPG. It manages to be both fun and severe, catering to casual readers while offering something more profound for those who wish to dig deeper.

The only downside? The wait for book 2, which, given the stunning conclusion of this first installment, can't come soon enough.

Five stars, unquestionably.

Fein did it again!

Mendel's ladder for me truly feels like the beginning of something big. the story threads presented in this first book are so intriguing to me its going to be very hard having to wait for the next iteration to come out.

the world building Fein writes really thrust my mind into this gory, visceral hellscape that earth has been transformed into by the big powers at play and I found myself constantly trying to think ahead to what plans they had in store for the world. and I still feel as if there are being behind the scenes pulling strings that I couldn't even begin to comprehend still to reveal themselves.

the world feels deadly dangerous and yet somehow beautiful with its sprouting vibrant life contrasted with the savagery of mutant animals and bloodlust hunters/huntresses who will stop at nothing to spill blood in pursuit of their eternal hunt.

On a personal note I wanted to thank ES Fein for allowing me to read this book early. I'm not particularly the best when it comes to reviews but for some reason have very much enjoyed the process of providing feedback however limited i might be in that capacity. So thank you so much for giving me the chance to read this ahead of its full release in October. I hope people enjoy it as much as I did.

Awesome and Immersive Science Fiction Story

Set in a futuristic dystopia in a world previously ravaged by war and climate change, humanity is just clinging on in a few remaining settlements but they have to deal with weird nomads, hybrids, mutants and scary hunters sent from a mythical space station orbiting the Earth. Shira and her wife Myriam, bad ass, Amazonian type warriors from Wintersvilla have to escort two girls who may hold the key of saving humanity to the underground city of Downver, but first they must contend with a weird metal man from a mythical city previously thought dead and a hunter and hunteress intent on wiping all of humanity out.
Meanwhile on Astrea, the mythical space station orbiting the Earth, lives the people who were lucky enough to escape Earth when the bombs fell and their future generations. Its perceived as a utopia but not far under the surface there is revolution brewing and Samuel unwittingly gets caught up in it. Desperate to get back to his family he discovers some startling truths that shatters his own existence. This is a cleverly written and fast paced science fiction story with an imaginative and complex plot and some awe inspiring twists. I was fully immersed in this story and I am looking forward to reading the sequel.

I was the winner of the ebook of this book on reddit. The author requested that I leave an honest review.

Whoa! I've never read quite a book like this. I loved the characters so much and I'm so happy that there will be more books coming out in the series. I love Shira and Myriam just talking around the fire after the battle. What a beautiful relationship they have and they are still fierce warriors too. I finished this book in a single sitting because I just couldn't put it down. Warning: the first chapter is very confusing, because, it introduces you to an alien basically, but it is very short. Then, the last chapter does the same thing and by then you totally understand the alien Nomad (not an alien from space, but they might as well be). A very fun but also very deep story with very well developed characters and a plot that drives you to keep reading!

This one blew my mind. I mostly read philosophy, but despite being part scifi and part fantasy, this book also had deep philosophy interspersed as well. Astrea was an extremely compelling concept. Through the character Samuel, Fein explores the process of disillusionment with "utopia" or in this case, a communistic orbiting space city. I greatly enjoyed the juxtaposition of the vastly different perspectives, from Astrea, to the wilds of the Earth full of lethal plants and animals. I am just very impressed that Fein was able to make something so action packed, original, bizarre, all the while ingrained with profound philosophical insights and explorations. This is an incredible story! Do yourself a favor and read it!

ES Fein definitely earns his title of lucid dream expert with this story. From page 1, you are left wondering what a flesh tree is and how Earth came to be this way. Throughout the story you are introduced to creatures that although they are described, they are not explained. This is the type of book where you are learning and piecing things together all the way to the last page. Although that isn’t my favorite stylistic choice, it is well executed.

The world is described in dramatic and, more often than not, gory detail. I am not normally squeamish but there were a few parts that made me cringe. This shows off the talent of this author. The complex politics draws you into each of the individual stories in the different points of view and hints at a larger conspiracy of how Earth was destroyed and how the “human” world adapted.

Mendel's Ladder is a blast!

I thoroughly enjoyed this book and spent several nights sitting up late with it. I particularly liked the relentlessly dark tone, an ongoing tension that propels the grim storyline without much reprieve. This is the sort of dystopian, sci-fi fantasy fusion that presents great challenges for authors to convey, and E. S. Fein handles it superbly. Belonging to a number of separate entities, the characters within are deep and have well-developed identities. They exist in an epic world I found deeply involving, and I came to admire everyone more or less equally. This story challenges readers by making it difficult to predict the future, to decide who might succeed and who might not, and wonder what the really big picture is and where it will all eventually go. This intrigue is one of the book's key strengths. It is a dangerous and miserable world that knows no peace. It comes complete with intense warfare and a mysterious, proprietary science that is well-considered and well-presented. The dialogues are colloquial and use a natural, contemporary language . For myself, I'm glad there is more to come, three more books in fact, for I am hooked on the story and look forward to finding out what happens. Appending Book 2 Chapter 1 to the end is a nice teaser. If I were to find a relative weakness, I would suggest a little more care in technical grammar and usage, though it seems to flow better as the story progresses. Anyway, in fiction, flexibility in this regard is needed, so the quibble is not a deal-breaker by any means. I think maybe I might play the Huntress Volya in an RPG campaign while the story could also be a pretty cool video game, with her up front!

**I read this book as a judge for the third annual Self Published Science Fiction Competition (SPSFC), this review is solely my own and does not reflect the opinions of the whole team**

CW: graphic violence, blood, gore, murder, torture, death, harm to a child
--

The writing kicks off being overly verbose but it eventually settles so that you can follow most of what is going on and picture what the author is trying to portray in this original take of a future earth/civilization.

The book mostly reads as a Science Fantasy story and the worldbuilding is extensive, partly fascinating partly horrifying. The action is well written but I’d say you should definitely take note of the content warnings before going in (especially for the violence).

There are about 3 POVs with other characters perspectives dipping in and they equally keep you engaged however, none of the characters are particularly likeable. This isn’t a bad thing but I also found that they never really had much development over the whole book. For one there is a short time frame so we don’t get a lot of time with them but they also seemed to have very similar traits. For instance excessive misandry is the primary characterization for all of the leading female characters. Also the established relationships very obviously have a lot behind them but you mostly have to the take the protagonists word for it through their inner monologues or the snippets of flashbacks rather than actually being show this.

It is a tense and entertaining read but at just over half way it becomes obvious that everything that has happened is more or less set up for the next book. By the end there is too much going on for it to be clear what exactly the set-up is for though.

I don't normally read action scifi and although this book is filled with action it is filled as well with a great philosophical depth on par with that of one of my all time favorites, Dune. Denis Mendel reminded me of Paul Atreides or Leto the God. I enjoyed the journals very much, and the action and (very) grimdark atmosphere was very well orchestrated and well thought out. The entire book culminates in a giant battle, and Fein really delivers on this ultra intense battle that it all builds up to. Very impressive story telling and characters that I felt very attached to and interested to see what happens next. While the book concludes what it all led up to, it does leave a lot of mysteries, so I couldn't help reading right into book 2, which was also fantastic! I'm excited to keep going with the series! Great for grimdark fans and scifi/fantasy fans, but in my case, for fans of deep philosophy as well.

At every point I am reading this book, I was thinking, wow, where could the author be going with this? What can this all lead up to? I read this book faster than I've ever read any other book. It was only the first chapter that was confusing, but I love the mystery and strange atmosphere that it creates with our first introduction to how the world has drastically changed. I don't normally enjoy action scenes, but there is an entire chapter in the book detailing one epic battle that everything leads up to, and I never wanted it to end. ES Fein is a great author, and I was fortunate enough to read an early edition of the second book in the series as well. I read book 1 and 2 back to back, and I wish book 3 was already available! Thank you for the chance to read this early! Please make sure to finish this series! It is incredible so far!

I purchased the physical copy of the book at a comic con. I finished it that same day. The reviews for the book on here say it perfectly already. Well done to the author, and best of luck with your writing career! This was an amazing book. I made a goodreads account just to hop on here and tell you! That was amazing! Well done.

This book was an interesting read. While it’s painfully obvious this is the author’s first novel, with its weird pacing, awkward plotting, and stilted dialogue. I still applaud the author for its sheer creativity. I respect a story that tries to do something different and truly work the authors imagination more then if it was a perfectly written generic story. For that I will continue the series and just hope the author gets better as he goes cause I am definitely invested.

Action was well done and the world building was amazing and engrossing.

If you're into sci-fi dystopias this book is for you. It is a multi-faceted nightmare of earthly expanse. The writing is excellent, and the storyline is riveting. It's a good read, the book is not too long however it is long enough to be very entertaining. It genuinely captures The human experience and generates an enormous collection of unyielding action and human emotion. This is a good book.

This in depth world that has been masterfully crafted by the author makes this book into a alternate reality that you don't want to leave. The pacing and character building is magnificent. I can't wait to see where this author takes us next, whether it be further into this world or another action packed sci-fi realm.

Wow. I had to put this book down twice. It is intense, and it’s a doozie. His world-building is insanely original. For better or worse, it’s like nothing you’ve read before.

Flesh trees? Human pods? Nomadic hybrids? Everywhere you turn, it’s cyborgs, humans, and or mutants desiring to attack and or kill everything in sight. It follows three characters: Shira, the cybernetic warrior; Volya, a ruthless engineered Huntress; and Samuel, a space station worker. I just finished the novel and am still astounded at its originality.

You’ll read dialogue and prose, I guarantee, you’ve never seen before (No spoilers.) The plot is multi-dimensional and needs a thorough read to stay with. This isn’t a book to read with television playing in the background. It’s not a casual read at all. It is dense and can turn on a dime. Also, it's definitely gory.

If you're looking for something original, well-thought-out, complex, action-packed, and gory, Mendel’s Ladder (The Collected Histories of Neoevolution Earth Book 1) by E. S. Fein is the book for you.

A build up of individual groups stories as they slowly intertwine together, culminating in a well crafted plot. Issues we see and live with in modern society are given a "what if" twist, showing a path of enlightenment out of the flaws of humanity. Mendel's historic journal entries dividing each chapter show his line of thinking, and tie in well to the events unfolding as his vision for Earth proceeds as planned.

The story is well written and detailed, describing even darker subjects well enough that you can truly feel for the characters involved. I look forward to what the rest of the series brings with the ultimate culmination of the central plot, but I am particularly interested in hearing more about the Hunter and his struggles!

I stumbled upon Mendel's Ladder and couldn't believe the wild and imaginative world it introduced me to. This book is like a mix of all my favorite sci-fi and fantasy stories rolled into one epic adventure. You've got cyber-enhanced warriors, bizarre human-plant hybrids, enigmatic Nomads, and ancient powers lurking in the shadows—all battling for survival in a post-apocalyptic Earth. The action is non-stop, the characters are unforgettable, and the plot keeps you on the edge of your seat.

Trust me, you don't want to miss this epic sci-fi journey. Mendel's Ladder is a rollercoaster of a read that's bound to leave you hungry for more.

This is the first I've read from this author and I love his style. He brings a lot of fun sci-fi/fantasy elements into this apocolyptic future Earth. The world building is excellent, with many really interesting types of people and creatures. It's relatively short, but he manages to accomplish a lot of storytelling in the world he's created for an exciting read. I can't wait to continue into Volume 2.

I never leave reviews. I tend to read, reflect, and move on. But something happened after I stumbled upon Mendel’s Ladder. It was like walking into a hidden library and discovering a dusty tome that seemed authored precisely for me. I felt compelled, no, obligated, to voice my thoughts. I made this account for the sole purpose of singing the praises of a series that has somehow flown under the radar.

Admittedly, Book 1 (Mendel’s Ladder) starts in a bizarre, almost disorienting way. It feels like you’ve been dropped into a foreign land with no map and no translator. But let me tell you, after reading the as-of-yet unreleased fourth book, that strange, off-kilter beginning makes perfect sense. In fact, by the time you reach the final pages of Book 4, you realize Book 1 was like a clever tutorial-zone in a huge video game. Fein was quietly teaching us the lore, the rules, and the philosophical underpinnings of his universe, all without us recognizing it at the time.

Now that I am starting to see the grander design four books in, I’m just blown away. Fein has an intricate plan for everything, including character arcs, shifting alliances, cosmic-level conflicts, and yet in Book 1, we’re merely dipping our toes in the shallow end of a bottomless ocean. Every conversation I’ve had with Fein (I found him on reddit) has left me more convinced that this series is on the verge of something monumental, a series that will be as big as my favorite series, Dune, one day. He’s remarkably kind, answering questions from random fans like me, which motivated me all the more to share my excitement. Because more people really need to read this. It’s that simple.

Now let me pivot to a more concrete review of Mendel’s Ladder itself, because while it does serve as an initiation into Fein’s sprawling mythos, it also stands on its own as a remarkable piece of storytelling. From the first few chapters, you get the sense that this isn’t just another post-apocalyptic sci-fi novel. it’s a carefully balanaced fusion of genres that carves out a space all its own.

The philosophical undercurrents in Mendel’s Ladder aren’t merely tacked on; they form the very bedrock of the story. The novel wrestles with questions of identity, evolution, and morality through the eyes of characters like Samuel, who lives on a utopian (and suspiciously uniform) space station. His initial comfort clashes with the grim reality unfolding on Earth below, prompting age-old inquiries: Are we the sum of our surroundings, or do we shape our environment through our conscience? Fein uses excerpts from Mendel’s journals to explore the concept of “forced evolution”, raising the unsettling possibility that science, once corrupted by power, can become a deity of its own making.

I’ve read my fair share of sci-fi, but the sheer enormity of Fein’s future Earth took my breath away. In this world, twisted flora and fauna, including flesh trees, half-human Nomads, and monstrous Mutants create a biosphere so radically different, you sometimes forget you’re reading about Earth at all. Think of it as a once-familiar setting recast in vivid, almost feverish detail. That shift in perspective is what makes book 1 feel overwhelming in the best way—like you’ve wandered into the wildest corner of the universe, only to realize you’re still on our home planet. I especially loved how Fein contrasts this ravaged, violent Earth with the seemingly idyllic realm of Astrea, a "utopian" station in orbit.

If you’re like me and you savor edge-of-your-seat confrontations, Mendel’s Ladder does not disappoint. The novel pairs gritty, personal struggles with colossal battles that feel almost mythic. Shira’s enhanced abilities and Volya’s lethal design make for combat sequences that push the boundaries of human (and post-human) capability. There’s a certain poetry to how Fein describes high-speed showdowns in Earth’s flesh tree filled wastelands.

Now I’ve seen plenty of sci-fi/fantasy hybrids, but Mendel’s Ladder stands apart in how thoroughly it melds grimdark atmospherics, high-octane combat, and layers of thoughtful world lore. It flirts with classic science fiction tropes like genetic engineering and post-apocalyptic ruin, yet is drenched in the creeping dread of a horror novel and the sweeping scale of an epic fantasy. The end result feels neither like a typical space opera nor a standard swords and lasers romp. Instead, Fein seems to have forged a new subgenre that I can only describe as “Philosophical Grimdark Sci-Fi”. It’s dark without being nihilistic, rich with world detail yet never short on existential inquiry. If that sounds like a lot to juggle, it is, but the payoff is remarkable.

Overall Analysis of Mendel’s Ladder:
Mendel’s Ladder (The Collected Histories of Neoevolution Earth Book 1) by E. S. Fein is a breakneck, grimdark, science-fiction epic taking place in a post-apocalyptic Earth where a mad scientist forces a cataclysmic event to precipitate evolution through harsh environments and technology. The story follows three main characters: 1) Shira, a cybernetically enhanced warrior traversing Earth’s harsh climate, 2) Volya, a lethal invention whose purpose is to wipe out the remnants of humanity, and 3) Samuel, an average, everyday worker aboard a utopic space station.

I have never quite experienced such unique worldbuilding. In fact, the worldbuilding was so comprehensive I didn’t quite wrap my head around many of the concepts until one-fifth of the way through the book. While I am not sure if that was intended, it did not affect my ability to understand the plot. Furthermore, once I understood the concepts of flesh trees, hybrids, nomads, huntresses/hunters, mutants, biofreaks, and the like, it really amplified the reading experience and allowed me to truly appreciate the incredible depth of Fein’s worldbuilding. Interspersed between each chapter are excerpts from the mad scientist’s (Mendel’s) journal that really helped me understand the more advanced and philosophical concepts of the story.

Though Mendel’s Ladder takes place on Earth, there is very little about our planet that is recognizable. The entire ecosystem has been restructured into a practically inhospitable hellscape for humans, dominated primarily by nomads (plant/fungus-like humanoids) and mutants (mutated animals). The characters that inhabit the Earth and the space stations, Astra, are wonderfully fleshed out. Despite not getting many chapters to get to know each POV, I felt an instant connection with each of the main characters.

Given the lethality, speed, and unimaginable destruction wrought by some of the characters in Mendel’s Ladder—namely the Huntress and her Hunter—it was initially difficult imagining how an actual fight would play out. The Hunter was described as having the capacity to wipe out millions of humans and nomads and travel at twice the speed of sound, so I was unsure what an actual battle with this creature would entail. However, the battle scenes were incredibly detailed, and Fein truly gives you a perspective of the high-speed and primal carnage.

Knowing that this was the first book of a series, I wasn’t expecting a satisfying conclusion. That said, many of the plot’s elements converged in a gratifying climax. One thing I would say about this book is that it seems more of an episodic installment given the length and the minimal chapters per POV, but this did not detract from my enjoyment.

Final Thoughts:
You will want to dive into Mendel’s Ladder when you are completely free of distractions. It requires you to pay close attention to the details to understand its advanced concepts and intricate world building. However, it is well worth the staunch mental focus as it is truly an epic tale. And even though I described it as an “episodic” entry into the series, the next two installments are already available, so you will not need to wait to discover what happens following the cliffhanger ending. Mendel’s Ladder, and the extended Neoevolution Earth universe, is a must read for fans of hardcore science fiction. The author, E. S. Fein, has an unmatched knack for unique world building.

Review: Mendel’s Ladder

⭐️⭐️⭐️⭐️⭐️

At a glance:

“Mendel’s Ladder” is a phenomenal read that is laced with action, unique ideas, and gorgeous writing. It takes place in a not-so-distant future after a series of catastrophes engineered by the madman Mendel who wants to “ascend humanity” past the evolutionary limits. In a lot ways, this is a science fiction, but it felt more like a fantasy with some sci fi elements as I read it. The story follows three separate stories, two of which have merged by the end of the novel.

What I liked:

The writing itself is beautiful. There are tons of details that I could paint the scene exactly in my head. The fights were amazing, the environments inventive and the characters realistic.

I also enjoyed the fact that we got multiple point of views. My favorite is the one with Samuel, despite me not loving the direction it went. My least favorite was Shira’s because I didn’t quite understand what her goals were other than protect two children.

I also really enjoyed the lore. I couldn’t follow every bit, but that’s normal for any book that has a lot of lore. I do wish it was slightly more clear, but the author has a website full with the details that I relied on. Furthermore, just some of the events that occurred in the past as well articulated and come across as actually possible.

What I didn’t like:

The biggest strength also serves as an Achilles heel in some regards. Most notably, although the descriptions were thorough and well crafted, it did border on too much at times. Additionally, there was a reliance on adverbs which isn’t a problem, but it did start to feel redundant. I want to emphasize though that this is a small problem that is not worthy of deducting any substantial value from the book.

Another thing I disliked was Volya’s dialogue. Although I completely understand her as a character, she had one insult for her Hunter the entire book and it was “dog.” This made the dialogue with her feel a bit unnatural as she kept calling her Hunter “dog” repeatedly.

Lastly and probably the most important part to mention: the book does not feel like a complete story, but rather .75 of a story. I don’t want to spoil it, but I think that if you’re looking for someone you can one off, this isn’t the book for you.

Concluding thoughts:

This book really captivated me in ways I hadn’t expected. I found myself wanting to read more about the lore, the characters, and to fall in love with the imagery that is pervasive in the writing. Although there were areas for improvement, this was a damn good novel, and I will be reading the next two.

Recommended to:

I would recommend this book to sci fi fans, fans really seeking a deep lore sink, and to people looking to break free from the monotone writings of they are stuck reading those.

Absolutely audacious. Have you ever been in a media funk? You know, where every piece of media seems uninspired, formulaic, and derivative? Well, do I have the cure for you!

Mendel's Ladder is perhaps one of the most creative if not the absolute most creative work of fiction I have ever read. Say what you want, but I've read a whole lot of science fiction and fantasy, and the vast majority of it is just blatant fan fiction of better and more prolific authors' works. That is not the case with Fein, not with any of his work. Based on creativity, audaciousness, and boldness alone, Fein is one of the greatest writers of our time. I don't say that lightly either. His prose is solid. It isn't going to blow you out of the water, but it has its golden moments. His characters are compelling. They aren't going to stay in your heart for the rest of your days, but they have their appeal and I enjoyed all of them to some degree. However, where Fein really shines is in wild, wild, WILD worldbuilding, lore, philosophy, and redefining genres (this is true of all his novels, which I read in a matter of a single week). It's hard to believe he is such an unknown author. I personally found him on reddit r/scifi, but even that post only had a handful of updoots. I think this is an utter shame. More people need to experience what it means to be thrown into truly alien worlds full of endless action, philosophical wonderings, and constant compelling moments.

A part of me started reading book 2 just to see if Fein would ever let us down. Spoiler: he doesn't. He is a master of his craft and I can't wait to see where this series goes and what new bizarre and tantalizing ideas Fein will serve us next!

This novel is a *lot* in all the best of ways.
It's rare to read something that feels simultaneously so ambitious and so well-realized. Nearly every aspect of Mendel's Ladder is a triumph: the pacing is lightning-quick and binge-readable; the writing itself is sophisticated, haunting, and utterly compelling; the characters are interesting; there's philosophical meat on these half-fungal bones. The world Fein has created has all the harrowing emptiness that made me fall in love with the 'Dark Souls' franchise; the pages practically ooze with implied lore, storied history, and audacious, fascinating detail.

I've read books where you could rip out a chapter, glue it into another novel, and a reader might not be any the wiser--so many books draw from the same tropes / have worlds that are built out the exact same way. Mendel's Ladder is so drenched in its own heavy mythos that even a single sentence from its length could barely work in any other book, and that's something I cannot praise enough. By the end of chapter one, I was fully convinced that I (and the story itself) was in great hands--and as the pages blurred by on my kindle, Mendel's Ladder quickly earned a place as one of my favorite indie titles I've read.
