Millennium Bug

Rate this book
David Smith’s life is thrown into chaos when a mysterious book crashes through his window, telling the story of a life he doesn’t remember. A stranger, claiming to be a hidden scribe who weaves reality, demands the book back, warning that keeping it will unravel the world, but returning it will erase David from existence.

As the ancient order of storytellers is threatened to be overthrown by AI, David must reclaim his past and rewrite destiny itself to prevent the erasure of all reality. But if he succeeds, the cost may be too great—unlocking the truth of his fate gives him the power to destroy everything, including the only man he's ever loved.

If the world was never meant to be real, does it deserve to exist?

This book is legitimately awesome and I loved it.

At the same time, this isn't your average book and it won't be for everyone. (Which is kind of a good thing.)

If you're like me, who loves the epic love story part of Good Omens, the wackiness of Doctor Who, and the light, satirical style of The Hitchhiker's Guide, this book was written for you. Next to all of that, the social commentary is on point, and that's really the best thing about it. It has everything entertaining going for it but it's also deep, and human, and wonderful. Just like the best stories always are.

(Also, the best Doctor Who episode is Human Nature. Fight me.)


Thank you to the author for trusting me with an ARC.

I am blown away by the world building and the absolutely effortless way it sucks you in. This story centred around The Library of All Things and Beings is unique and gripping with wonderful characters and cheeky humour poking through that just didn’t let me put it down. There’s a twist and a mystery around every corner and there is a race against time and all powerful beings that are coming to destroy life as we know it. David, Two and Hope make unlikely saviours but saviours they are. Specially when joined by Feri. But also David is not who he appears to be and who is could be mind bending for this whole saviour arc.

David’s very very unimaginative life (if you don’t count the reading kink up) is upended when THAT book comes flying through his window, closely followed by Author Two. ADVENTURE is what keeps chanting through my mind as I read as fast as I can to go on this epic journey of portals and fates and lost friends, soulmates and bubble tea and celebrities and books that are anyway a magic portal arnt they. I also found the book repairer adorable.

Then there is Vylan. I have complicated feelings about them so we don’t need to go into that. Trust me when I say they are as they should be.

With elements pitting them against each other Vylan and Two are truly locked in a dance to the death. And yet at it’s core this also a story of epic everlasting aeons of LOVE!

Gosh I wanted to discuss this story and it’s twists so much with someone.. quick read it and DM me!

There is a lovely warmth rich with emotion that starts evolving and gathering as the story goes on, built on friendship, love annd loss and it’s what keeps you firmly anchored, fully invested. That ending.. I need time and carbs to digest it.. I should have heeded the advice at the beginning of the chapter.

I love the metaness (sorry for the non word) of it.

"Books are only meant to hit you emotionally - but there he was, sprawled on the floor, surrounded by shards of glittering glass."
So, this book predicted that it would also hit me emotionally and mentally and a little bit physically with the very first sentence of the first chapter. I haven't read a single book in couple of months and this book was exactly what I needed right now. It has Doctor Who vibes, lots of pop-culture references sprinkled deliciously throughout the whole story, the characters are mostly likable and lovable, and somehow I even ended up liking the hated character. I thought I knew what I would get just by looking at the curious cover, and let me tell you, it's so much more fun than I expected, I loved how it was about Y2K being the year that Earth was supposed to end and we are here now because one character, named Two did some meddling and saved us.
"She felt as though she was trapped in a cycle of mediocrity, unable to break free from the belief that she was boring and uncreative."
As someone who can deeply relate to that quote, I loved Hope and wanted to hug her.
So there's a computer that will reboot our world again and everyone is trying to not let it happen and we get some serious DW vibes all around and then that ending! I will not spoil it but I was crying and smiling and that was honestly perfect ending and I feel I got a hug and a smack at the same time from this book. I don't think I can describe everything that I loved about the sci-fi fantasy book with the queer characters and timey wimey stuff and all the feels it gave me. So I hope you read it and enjoy this wonderful journey.

“The chosen one has been a teenager way too often. Time for two boomer-looking blokes and a brown woman to save the world.”

What a book! It made my geeky bibliophile heart very happy. It’s been a while since I read a book where I focused on every description, every detail, but Yvonne’s writing is just so much fun!

The book has no many references to Doctor Who, Lord of the Rings, Hitchhiker’s Guide to the Galaxy and all the others that make a geeky heart beat faster! The characters are all unique and you just want to hang out with (most) of them (and play a the game of life with them).

And my new favourite way to say I love you: ”if one can find the warmth of home in a book, then you are my library.”

3.5 ⭐️ Millennium Bug is a creative and whimsical fantasy that explores a world where every living being has an Author and the fate of Earth depends on a mysterious book and a guy named David. The story's imaginative premise immediately draws you in, and the blend of fantasy, mystery, and emotional depth keeps it engaging throughout.

I especially appreciated the LGBTQ+ storyline, which is woven naturally into the narrative and adds meaningful representation. The main characters feel like your average, everyday people which makes their journey all the more relatable and heartfelt.

That said, some parts of the story felt repetitive and the pacing slowed down in places, making the book feel longer than necessary at times.

Still, the originality of the world building and the emotional connections between characters make this a worthwhile read for fans of whimsical and thoughtful fantasy.

Life has decided, it’s about time that the seemingly forgettable, middle-aged David Smith took notice of the clues. A day that began with an ‘accident’, morphed into something few could have imagined – but someone did.
This is a tale that drew me in. It began with an ‘UH’ note, then ‘OH,’ and finally ooooohh. It’s a bit like The Whacky Races meets Doctor Who, where the only answer is 42 and all the chapters are kept in a library somewhere in the universe. This isn’t just an excellent story in a well-worn genre; it's a style of story I’ve never encountered before. Believe me, that's no small feat, given how many books I’ve read in my lifetime. Millennium Bug is the kind of tale where you should get your tea and biscuits ready before opening the cover. It’s a wild ride.
The story is told in the third person, past tense, from the narrator's point of view. Usually, multiple voices aren’t well received, but I’d give this one a pass because I don’t believe it could have been written any other way, and there’s a reason why the author does it like this, which you will have to read to discover.
I’m not going to say too much about the characters or the story, as too much about anything will give the game away, but if you decide to read this novel, all of it will make sense at the end, which is why I describe the tale as a wild ride.
Okay, so here goes.
Gender is usually 'they' but can be anything on any given day. That is, unless your name is Holly, and Two is more than just a number. Humor is dry, wacky, and some of the best I’ve read in a long time. Being human is a nice-to-have; anything else is best described as a cosmic entity. Originality is abundant, and I loved some outlooks on life. Triggers exist – but not on firearms.
The story begins in a board game shop in the UK. From various parts of London, you can reach other areas of the cosmos that hold influence. Confusion leads to chaos, and inner turmoil follows, while mysteries are unraveled, and an eclectic quartet strives to save the earth. Meanwhile, 1999 is more than just a song by Prince.
Oh – I almost forgot to give a shout out to the book repairers.
In short, get your head in the game, keep focus, and by the end, you may be asking the question, Could AI take away the freedom of creative writing?

I’m not quite sure how to start this review without sounding like someone’s thrown a book at my head (literally, like what happens to David, the main character), but here we go: this story is absolute madness… and I loved it. It’s one of those books that grabs you from the first page with a tone that’s equal parts absurd, heartfelt, and philosophical—like Douglas Adams and Russell T. Davies had drinks with Terry Pratchett and decided to write about the end of the world… with glitter.

The story begins with David, a grey, forgettable man who can’t read (literally), until a mysterious book with his name on it crashes through his shop window and changes everything. From there, the narrative becomes a funny, tender, and surreal journey that blends cosmic libraries, authors who write people’s lives, the world rebooting every time we hit the year 2000 (yes, the Y2K bug was literally a narrative glitch), and a beautiful exploration of identity, memory, and what it means to have a story of your own.

One of the highlights of the novel is the dynamic between David and Hope, his assistant: she’s witty, sharp, and has a much bigger heart than she lets on. Their dialogue sparkles with humour and humanity. And then there’s Author Two, a cosmic being disguised as a human who shows up to collect David’s book… and unleash even more chaos.

But beneath all the humour, geeky references, and Doctor Who nods, Millennium Bug is also a deeply emotional story. It talks about grief for oneself, the fear of forgetting who we were, and that longing to reconnect with whatever makes us us. Some moments will make you laugh, others might leave a lump in your throat.

If you enjoy original stories, crumbling realities, complex queer characters, and books that laugh at themselves while still making you think… this one’s going to blow your mind. 🌀📚✨

Thank you, Yvonne, for sending me this ARC of the book. This story feels like it’s been written for me ❤️

If you want to get this book, it’ll be available through Amazon on the 15th of September!!

Entire review @Joyfully Jay

3.5⭐️


Earth exists in a perpetual cycle of reboots, restarting at the end of 1999. These cosmic resets are run by the Congregation of Fate; it also oversees the celestial authors from the Library of All Things and Beings who write a book for each human’s life. The authors repeat the individual’s storyline with slight deviations each time, and their books are collected when their life is over.

After thirty-six reboots, the leader of Fate, Vylan, decides to replace authors with an AI computer. A hard reboot to Earth’s first edition with no more revisions. Author Two decides its time to change the story, not regurgitate it verbatim. In Two’s impulsive and dramatic style, he devises a way to thwart booting up the computer. . . but there’s an unforeseen bug.

This is an entertaining mix of the magical, mundane, and a loop of avoidable inevitability inherent in navigating the whims of cosmic beings. David finds contentment in his glitter pens, board games, and nerding out with Hope, but for forty-odd years, he has lived without living. Hope worked hard to fulfill her lauded artistic potential, but she lost touch with herself and her creativity. She’s accepted her mediocrity and settled into her life with her odd friend and their odd shop. . .

Vylan and Two are the OG grumpy/sunshine pair—except Two is a cheeky rebel that Vylan wants to scrub from existence. . . Their ‘frenemies-more than friends-not really-but yes actually’ connection shouldn’t be possible, but for billions of years they’ve increasingly drifted into each other’s orbits. . .

Millennium Bug starts very strong and has cooky charm, but at some point, it became less charm and more schlep. The parentage of the book is stamped heavily into it and, in a story about the unoriginality of AI and reboots, it may be poetically meta to some that occasionally it has the air of a “write this in the style of Pratchett and Moffat” ChatGTP prompt. . . Kudos for the ending though.

A quirky, absurd, and heartwarming story that gave me The Good Place vibes. Fun pop culture references, unique characters, and a surprisingly wholesome romance made it heartwarming, even if the pessimistic ending didn’t quite fit.

"Being an evil leader with an identity crisis was hard"

I had such a fun experience reading this book, which was surprising, since I’m not a fan of The Hitchhiker’s Guide to the Galaxy. This story felt like it took the absurd, nonsensical energy of that kind of humor but added just enough pop culture references to make it relatable without being over-the-top. And I loved that it had a bit of a queer, modern twist.

The plot was absolutely absurd, almost nothing makes sense, and I loved it. From the very beginning, I could clearly picture the protagonist. He isn’t conventional, but that’s what made him perfect for this story: just a very normal millennial guy running a board game shop and geeking out. I especially enjoyed how none of the characters fit the usual fantasy molds. Each one felt unique, memorable, and refreshingly different.

One thing this book did really well was weave in a romance. It was important and meaningful to the story, but never felt like filler. I rarely enjoy romance in books, but this one was adorable and wholesome.

My only downside was the ending. It leaned a little pessimistic, which didn’t quite fit the otherwise warm, chaotic vibe of the story. It felt more like an add-on than a natural conclusion.

Overall, this book reminded me a lot of The Good Place: funny, quirky, and surprisingly heartwarming. It left me feeling happy, cozy, and entertained.

📚 BOOK REVIEW ~ Millennium Bug by Yvonne Knop 👾
***RELEASE DATE: 9/15/25

I just completed my first-ever ARC, and I’ve gotta say that I enjoyed every minute of it!

‘Millennium Bug’ is a wildly original story that is both tons of fun and quite timely. Fast-paced with great characters, high-stakes drama, and incredibly creative world building, this story is honestly completely different than anything I’ve read in recent or distant history. The unique synthesis of cosmic sci-fi with elements of fantasy echos the likes of ‘A Wrinkle in Time,’ but for a grown-up generation with an eye to the future.

The characters are diverse, with people of color and queer individuals portrayed sensitively and authentically, and the Y2K throwbacks are likely to be relatably nostalgic to anyone who lived through the infamous (and quite anticlimactic) turn of the millennium at midnight on January 1, 2000.

Underneath it all, there are thought-provoking musings on Fate vs. Nature vs. taking the reins and becoming the author of your own story. And the story arc involving the authors serves as a highly relevant, metaphorical cautionary tale as we enter a very scary era with AI and its (unfortunate) role in future storytelling.

I highly recommend this story to anyone looking for something completely original and unique — it beautifully reflects its own message about the level of creativity a living, breathing mind is capable of. Thank you so much for this opportunity, @ , and congratulations on the publication of such a phenomenal story! ⭐️⭐️⭐️⭐️⭐️/5!!

Millennium Bug by Yvonne Knop, publishing 16th September 2025 in the UK.

Wow, what a fun, original book! If you grew up watching Doctor Who / Sarah Jane Adventures (UK folks) this is especially for you!

David Smith runs a board game shop with the help of Hope, one day everything changes when a book crashes through the window and knocks him over, it claims to be the story of his life but he doesn't remember any of the events within it. Actually, what does he remember about his life?
From here we are introduced to some alien characters to help David on the mission of surviving the relaunch of Earth by the computer (AI), and try to keep the order of storyteller authors to prevent monotony on Earth.

The story touches on AI but in a way that isn't too in your face, and with a great plot... like really great plot!

This book is funny, intriguing, romantic, adventurous, and thought provoking. It is a really fun ride which I would recommend to most people, even those who do not necessarily dabble in Sci-Fi (don't be put off by the mention of AI, it is handled perfectly!!).

Expect: found family, light romance, friendship, aliens, adventure, quest.

Thank you to NetGalley for the e-ARC of this title.

Disclaimer: I have read an early copy of the book via NetGalley, thank you!

My first impression of this book after reading the synopsis was hey, this looks extremely fun.

I was right. Sometimes a book feels like written just for you and this is exactly this kind of book. The story is very fast-paced and it never got boring once, the characters are fun, quirky and have great dynamics with each other. The relationship between David and Two is a delicious mix of longing and slow-burn, The worldbuilding is insane and a breath of fresh air.

One of my favourite things about the book was the writing style - fun and easy, making the whole story feel almost cozy while not taking away the severity of some situations the characters found themselves in. While it may not be for everyone, I adore when the narration doesn't take itself so seriously. Some people may also be turned off by a lot of nerdy references, though it didn't bother me at all.

If you want a cozy but action-packed sci-fi story with queer romance and characters that are over 30, look no further. I hope Millenium Bug gets all the love it deserves.

Knop’s ability to make the story feel comfortable and familiar is notable and makes Millennium Bug an entertaining read. I’m sure many who like a blend of satirical silliness, beyond the dawn of time levels of pining, and characters with a talent for tripping upward into a solution will enjoy it.

Millennium Bug is written very much in the voice of A Hitchhikers Guide to the Galaxy or Good Omens, both are referenced in the book as a bit of a wink-wink-nudge-nudge from the author. The writing style and point of view is from an almost omnipotent yet, hilarious perspective. The premise is that our reality is written by a bunch of Authors floating around somewhere in space, maybe a different plain of existence in a library, directing our lives. If everyone’s life is a story in a book it would be a little awkward meeting the author, but one author has come down to collect an overdue book. Hilarity ensues, it turns out The Authors are being replaced by a machine, Fate has a “great plan” that The Authors keep messing up, so after 36 versions of earth they will be out of a job. Timely allusion to AI anyone? There is an underlying love story, it’s super low spice with a bit of angst, but nothing heavy as both the setting (a game shop) and the characters are very whimsical.

Please note, I received an ARC copy of this book for review from NetGalley, but that never influences my honest reviews of books or authors.

Millennium Bug by Yvonne Knopp is a Doctor Who-esque sci-fi with high-stakes the-world-is-gonna-end vibes, but make it sweet, silly, and fun. It's an absolutely wild ride with lots of twists and turns and characters that you will love (and also maybe won't love so much For Reasons). 🤣

Knopp brings quirky humor to a story that challenges Fate and how our stories are written (literally) while giving us a whole ass found family and some gender fuckery.

You'll laugh, you'll kick your feet, and you'll ask yourself, "What the fuck is going on?" (Lovingly)

This is a fantasy and what a wild ride.
It's kind of tripping. Lol
There's a lot going on and several twists and turns.
I liked how it was about authors of life and when it was time to shelf you the author came for your book.
When Two shows up to collect David's book it gets complicated.
Like I mentioned there's several twists, lots of humor and it does keep you on your toes. The ending did get to me and made the story. I loved the little book repairers.

This was weird and creative. I LIKE weird and creative. I mean, The Hitchhiker's Guide to the Galaxy is one of my favorite books. But, unfortunately, something about the dialogue didn't flow very well for me and kept tripping me up while reading.
