I was just an anonymous clerk at a game store. Then one day a disgruntled customer ran over me and my hot co-worker Kelly – all because of an unreleased game I wouldn’t sell him.
Now we’re trapped in a huge three-dimensional maze where gravity seems optional, competing in dangerous contests with a team of fellow social outcasts.
And failure is often fatal.
But I think I know what’s going on here. We’re gathering territory, I’m gaining strange abilities, and every contest we win adds another member to my team of hot girls.
We just need get to the bottom of this maze. If only we can find it.
The Escherian Core is is a dark base-building isekai gamelit adventure with graphic violence and unconventional relationships.
Michael Dalton is a professional journalist and editor.
Michael wrote his first piece of fiction in third grade, for which he was immediately accused of plagiarism by his teacher. Since then, he has been writing more or less steadily, interrupted only by occasional demands of work and family.
Michael lives with his family and multiple pets in Southern California.
From anyone else, this would be a four or five star book.
Harem books can get a bad rap. Cheap narratives, flat characters and unrealistic relationships being the reason why. Dalton books do not have this problem. They have well built worlds with diverse and interesting characters who form realistic, believable bonds. And now here we are. Given the set up, I did not expect much of a world state, that's fine. The neuro divergence is such a defining characteristic that several of the characters seem "samey" with only a race change to differentiate. The instant bonding removes the believability with the dreams coming across as an "after the fact" patch. While all of this does not make this a bad book, it does lessen it severely.
The Escherian Core (Neuro-Divergence Book 1) offers entertaining and clever twists to the “I woke up in a strange place after being killed, and now must fight for my life while building a team of hot women” trope.
Initially, I didn’t care much for the male VA (Trevor Jordan) in this book…he performed the part of male gaming slacker just a bit too well. Once he was killed and became an integral part of building a team, his voice (and those of the other male characters) grew on me; he actually did a terrific job! The female VA (Alyssa Poon) was fantastic with all her roles.
Much of this story reminded me of David Burke’s terrific “Descend” series. Both series require the characters to advance in the “game” or die, the women all have distinct personalities, and we don’t find out until later in the book/series much about who is directing the deadly events, or for what reasons.
Also, as in “Descend”, we find the MC and his harem drifting back and forth in timelines, or here….alternate universe earths, and getting memories confused with what is a dream and what is reality. If you liked “Descend”, you’ll enjoy “The Escherian Core”. It’s definitely its own story!
Some of the challenges in the story were so hilariously over-the-top I was also reminded of the terrific Star Trek spoof “Galaxy Quest”, where the characters questioned the absurd challenges confronting them! Oh, and there’s a specific Stargate SG-1 episode that you’ll recognize, but I can’t mention it because of spoilers. It’s a great episode, though!
In addition to many action sequences, there are plenty of well-done intimate scenes too! No FTB here, I’m happy to report! The writing is intelligently done, and even uses the Fibonacci Sequence to solve a puzzle!
Well, I started writing more about The Escherian Core, but everything was coming up spoilers. So, let me just encourage you to get this terrific audiobook and enjoy the story yourself! Definitely a 5* book, and I look forward to the next book in the series: The Kafkaesque Passage. Oh, btw - author Michael Dalton has several audiobooks available on the US Public Libraries affiliated website Hooladigital.com, and the subscription site Scribd.com. Those books were published by Tantor Audio. Escherian Core is published by Royal Guard Publishing and the audiobook is exclusive to Audible. Given the dual narration gained, I applaud the move to the different publisher!
I was given this free review copy audiobook at my request and have voluntarily left this review. Receiving a review copy did not influence my rating or my review.
Not sure where to start, this was surprisingly very good and engaging.
The story itself is a huge mystery, of which only a small part seems to have been revealed to us, but enough to feel satisfactory. Basically people from all over the world/worlds have been gathered in a "cube" like experiment, having to defeat other teams and solve various puzzles all while making their own team stronger through bonding and receiving new abilities. Not all relies on using brute force, in fact quite a lot depends on using knowledge and especially by thinking outside the box. More can be said, but that would be going into spoiler territory.
The MC is likeable and avoids a lot of the tropes we usually see in these type of novels which was quite refreshing. the FL's are also very fun and unique in their own ways. Maybe the building of the team could have been done more slowly, but it kinda works like this also, and makes me wonder how it will develop in the future, while keeping all members relevant (hope this aspect will count in future books). The bonding ability was also quite fun and kept things interesting in that department.
Now for the narration. Alyssa Poon did an amazing job with the female characters, they all sound like different people with various accents and inflections, I could tell all the time which character spoke with it having the need to dwell on it. She also made them feel real and adorable in various ways. Trevor Jordan was also a good pick for the main character, but his role was a bit easier, so to say.
In the end it's a very good book that successfully combined both elements present in the genre while keeping us engaged and entertained. I really hope the next books live up to the hype because I'm quite excited for the next books to come and want to see more of these characters.
Yeah this piece of work is not for me. Short summary up until 27%: People die from accidents or whatever, and get put into teams of 6 in some weird system-ish world. They all discover that they have some mental disability and are set to complete "tasks" which basically equates to intelligence tests. There are always 3 pairs of men and women in each team, and each pair knows each other - The men (except protag) die off and the protag collects a harem that loves each other within an hour of their best friends dying.
Author MD definitely can write without worrying about grammar issues or general bad writing, but this story is just.. off. It's probably the worst quality cheap harem collection smut novel I've read in a while simply due to its absurdity. If you're gonna write a smut novel, do you really have to go through the following procedures? Isekai into a weird ass multiverse labyrinth > Kill off males > Show how smart the protag is due to being able to solve some math problems > Use some voodoo magic game system to make them all have sex? You really don't. It's just weird.
Overall, I really can't recommend anyone to read this. It's just straight awful.
Had a hard time tagging this one, but it's at least adjacent to the tags I used. I like the author and there was nothing glaringly wrong here, but IMO not his best work.
As someone with two "neuro-divergent" children I appreciate that element of the story, but it overall was missing the je-ne-sais-quoi which would push it to a 5. The TL:DR (bit late in the review, but hey): it's an easy read and not too bogged down in sex for a harem book, so if you like the author's other work you may also enjoy this. It passes the essential "will I read the next one?" test, so that's what really matters.
Creating a world based on Escher, twisted death games and challenges with lethal consequences for failing is definitely one thrilling read.
Add in the odd abilities, unique and interesting characters with sometimes strange and unusual pasts makes it even more interesting. Especially when they are gorgeous women.
And the title of the series is truely unique and brilliant, and especially relatable to someone who also suspects they re "neuro-divergent"
A Dark GamLit Puzzle Box With a Troubling Core Premise (3/5 Stars)
If you scroll through Kindle Unlimited's fantasy section, you'll see no shortage of books promising an overpowered hero, a deadly game, and a loyal harem. The Escherian Core by Michael Dalton is exactly that—a competently written, puzzle-focused entry in the genre. The hook is solid: an unassuming game store clerk is killed and reborn into a bizarre, ever-shifting maze where he must lead a team through lethal challenges. It's fast-paced and brainy fun, earning a respectable 4.24-star average on Goodreads. However, the book's defining feature—its use of "neuro-divergence" as both a plot device and series title—proves to be its most significant and problematic flaw.
Key Themes Puzzle-Solving as Survival: The core appeal is the intellectual challenge. The protagonist and his team don't win through brute force but by solving complex, often mathematical, puzzles within a surreal, M.C. Escher-inspired labyrinth. This focus on clever solutions over simple combat is the book's standout strength.
Found Family & Team Building: Thrown together by circumstance, the group of social outcasts must learn to trust and rely on each other to survive. The narrative explores how bonds form under extreme pressure, though the speed and nature of these bonds (particularly the romantic ones) are a major point of contention among readers.
A Problematic "Neuro-Divergent" Power Source: The series' central conceit is that the main character and his teammates all possess a form of neurodivergence (like ADHD or Autism), which grants them unique cognitive abilities within the game. While an interesting idea, the execution is where the book stumbles. As one critical review noted, the neurodivergence often feels like a "defining characteristic" that makes several characters seem "samey," differentiated mostly by race rather than deep personality.
Character Analysis The story is told from the first-person perspective of the unnamed protagonist, a likable enough everyman who grows into a strategic leader. His development is standard for the genre: from victim to empowered player.
The female characters, however, are where the book's genre conventions clash with its loftier themes. They are intelligent, capable, and each has a distinct archetype (e.g., the logical engineer, the fierce fighter). Yet, their rapid, system-facilitated bonding with the protagonist pushes them firmly into "harem" territory, which many felt undermined their individuality and the potential for more organic relationships. The neurodivergent traits, rather than making them feel more real and complex, were criticized by some as a superficial layer that didn't translate into meaningful, diverse characterizations.
Writing Style & Pacing Dalton's prose is clear, functional, and highly readable. The pacing is brisk, with short chapters that quickly cycle between tense puzzle sequences, action, and team interactions. The book doesn't waste time; you're dumped into the mystery of the maze alongside the characters and the plot maintains a steady, page-turning momentum. The tone balances dark stakes (failure is often fatal) with moments of wry humor and camaraderie.
What I Liked/Disliked Liked:
The Puzzle Design: The intellectual challenges are creative and satisfying to solve alongside the characters. The use of concepts like the Fibonacci sequence is a clever touch.
The Genre Execution: As a dark, base-building gamelit adventure, it delivers precisely what it promises: a fast-paced, video game-like progression system and a compelling central mystery.
A Solid Cliffhanger: The ending effectively sets up the next book in the duology, The Kafkaesque Passage, leaving you curious about the larger conspiracy.
Disliked:
The "Neuro-Divergence" Handling: This is the book's biggest issue. What could have been a thoughtful exploration of cognitive diversity often feels like a convenient power-up system. For readers seeking authentic representation, it may come off as reductive or even exploitative.
Instant Harem Dynamics: The romantic relationships form with unbelievable speed, facilitated by game mechanics. This can feel inorganic and undermines the potential for deeper character development.
A Divided Ending: Some readers felt the final explanations were rushed, leaving too many questions unanswered even as it teased a sequel.
Conclusion & Recommendation Final Verdict: 3 out of 5 stars. The Escherian Core is a well-constructed and entertaining genre read that ultimately fumbles its most ambitious idea.
You should read this book if: You're a fan of puzzle-based LitRPG or gamelit and enjoy stories like David Burke's "Descend" series. If you're explicitly looking for a harem fantasy with a sci-fi twist and don't mind tropey relationships, you'll likely have a good time. It's a fun, brainy binge.
You should skip this book if: You are seeking thoughtful, nuanced representation of neurodivergence. The handling of this theme has been criticized as shallow and potentially problematic. Also, avoid it if you have no patience for rapid harem-building tropes.
Think of it as a competent genre vehicle with a problematic bumper sticker. The ride is fun, but the messaging might leave a bad taste for some. If you're in it purely for the maze and the mechanics, you'll likely be satisfied enough to check out the sequel.
It's ironic that the author decided to make fun of a neck beard on the first page when the story is about one. The story reads like it was written from a very sheltered point of view that is decades out of touch and suffering from a poor understanding of the opposite sex. PS: no one has used the word geek as an insult in like 20 years.
This is by far my favorite cast of characters in one of his novels and I'm very much looking forward to the rest of their story. The book also sets up an overarching plot that is interesting and has a potential end goal, instead of the nebulous goals of the mcs of his other 2 major series.
Easy and interesting to read, but really "odd" most of the way through, just dumped into the situation, and no real answers or understanding start to appear until the very end. So if you find yourself enjoying the writing, but wondering what is going on, keep with it, it becomes a bit clearer in the end :)
So, full disclosure - I was also diagnosed with ADHD, know around here as, "Attention Deficit..... Hey! Let's Ride Bicycles! "
The idea the it could be a world saving super power is a weird one for me, but it works here. I am looking forward to book two so that I can see where this goes.
Look, yes, this is exactly what you would expect from the cover.
Other than that it's actually not terrible. Up until the final couple of chapters it was basically a kind of horny take on the movie Cube. A bunch of strangers forced to work together to resolve weird puzzles in an almost impossible space. The mystery of the setting was kind of compelling.
Enjoyed this, I liked that the plot idea was so different from the other gamelit books that I am used to reading. Trying to envision the structures in the maze was difficult sometimes but will look forward to next book in the series. Also I thought that the pictures throughout was a nice touch and hope it continues in the next one.
This story is much better written than almost off this genre. I honestly care about the MC and all the girls. It's not all about some guy beating everything with girlfriend helpers. He sits back whoever is best for a challenge runs the time. They make bonding action logical to the story. I finished this book in half a day.
I liked the alternative nature if the characters in this story. The pace is fast, and developed into a deeply immersive experience quickly. Great read, and I can't wait for the next.
Big fan of this author and this book was no exception. Great concept and great execution with lots of action but not done in a way you expect. Definitely going to read the next one.
Well written harem building story. Not quite a stroke story.
Much to recommend in this tale which uses an Escher like backdrop. Would have preferred more story and less sex, but the neurodivergence aspect may not resonate with neurodivergent people.
Neuro-Divergence Book 1 is an awesome read. Definitely can’t wait to read book 2! If you are into science fiction like me you will definitely like this new series!
This is a good book. You shouldy read it. I like the story. The characters are fun. The book is a good read. i enjoyed it alot.. Download or buy it today. why not?
