The Two of Us at the End of the World
A deeply moving story about resilience and hope that bridges the gap between the end of the world and its aftermath as four unforgettable characters try not only to survive, but to preserve the very thing that makes life worth saving in the first place. From the acclaimed author of A Boy and His Dog at the End of the World.
What if one person was your whole world?
In the overgrown ruins of a world almost empty of people, the only person Mouse has ever known is Cat, the brave girl who carried him inland, away from the sickness that came from the sea. When strangers arrive with a choice to be made, nothing will ever be the same.
Almost two hundred years earlier, a couple are falling in love as the world is dying out. When they discover they are two of the few people still able to have a child, so do the authorities. They may be separated from Mouse and Cat by an insurmountable gulf of time, but some truths family comes in all shapes and sizes, so does love.
And even at the end of the world, hope dies last.

I adored A Boy and His Dog at the End of the World, so I was very excited to find out there was going to be a companion novel.
My favourite end-of-the-world stories are the quieter ones — where people have to adapt to being alone, or almost alone, in a world where everything familiar has disappeared. I’m much more interested in the emotional side of that than in constant action: the isolation, the loneliness, and the way people slowly learn to live with nature rather than apart from it.
Mouse was especially interesting to me because he has never known anyone or anything other than Cat and this way of life, so his whole understanding of the world is shaped by that isolation.
I didn’t dislike the Boy and the Girl chapters, but I’m not sure the story really needed them. I also think a stronger sense of purpose or mission might have given the ending a bit more impact.
Still, I’m really glad I got to spend some time in this world again.
The Story: In a near-empty future, Mouse and Cat have only ever had each other. Nearly two centuries earlier, another couple discover they may be among the last people still able to have a child, linking two stories about survival, family and hope.

Review of advance copy received from NetGalley
**Sometimes you can admire what a book is doing without being able to stay with it.**
## ✶ PRE-READING ✶
I was immediately drawn to the premise of *The Two of Us at the End of the World*, particularly because I've enjoyed other books by C. A. Fletcher that explore the end of humanity through mass infertility. Fletcher also has a habit of putting some Very Important Dogs into his stories, and I am absolutely not going to complain about that particular authorial signature.
The two-timeline structure also intrigued me. I liked the idea of seeing the end of the world from different perspectives and watching the pieces gradually fit together.
## ✶ POST-READING ✶
**As I thought...** there is a lot here that I liked. Fletcher has a real knack for making the end of the world feel personal rather than simply spectacular, and there are some lovely meditations on family, belonging and what we owe to other people when the structures of society begin to disappear.
The two timelines are particularly clever. One narrator's sections deliberately abandon some of the conventions we are used to seeing in fiction, because he has grown up having encountered only one other person. The rules of dialogue and storytelling that feel natural to us simply aren't meaningful to him in the same way.
I understood exactly what the formatting was trying to achieve.
**It still made the book harder for me to read.**
That distinction matters. I don't think the choice is inherently bad, or that it shouldn't have been made. In fact, I think it's an interesting piece of storytelling. It just meant that I was spending more effort working out how to read the page than I wanted to, and eventually that became a barrier between me and the story.
I read around 32% before putting the book down, and although I later skipped ahead to around 85% to see where things were going, I wasn't finding myself drawn back to it. There was plenty here that I admired, but admiration wasn't quite enough to make me want to keep reading.
There's also an interesting possibility that this belongs to the same world as *A Boy and His Dog at the End of the World*. There are enough echoes to make me wonder, although there's no real way to know from what I've read—and I certainly wouldn't want to claim a connection that isn't there.
I suspect this will be a book that works extremely well for some readers. The ideas are strong, the structure is inventive, and there is real emotional thought behind the story.
It just wasn't enough to keep me attached to the book.
## ✦ RECOMMENDATIONS ✦
**Book Recommendation:** *A Boy and His Dog at the End of the World* by C. A. Fletcher, particularly if the combination of post-apocalyptic survival, human connection and Very Important Dogs appeals to you.
**TV or Movie Recommendation:** *Station Eleven*. Both are interested in what remains of humanity when the world as we know it disappears, and in the relationships and memories that become more important when everything else falls away.
## ✧ VIBE CHECK ✧
**A colour palette:** faded blue, weathered grey and the green of things stubbornly growing back.
**A soundtrack:** sparse piano and distant, echoing vocals.
**A season:** late autumn, when the world is becoming quieter and you can feel winter approaching.
**A mood:** melancholy, thoughtful and quietly hopeful.
**A scent:** wet grass, old paper and woodsmoke.
## Final Thoughts
I read approximately 32% of *The Two of Us at the End of the World* before deciding not to continue, although I did skip ahead to around 85% to get a sense of where the story was going. As such, this is a DNF review rather than a review of the complete novel.
*The Two of Us at the End of the World* publishes in **March 2027**. I received a free copy via NetGalley and am giving an honest review.

I read Fletcher’s previous novel (set in the same world as this one) a few years ago and loved it. I feel the same about this novel. I was so happy to be placed back in the same setting and find out more about *why* there weren’t as many children. I’m not sure exactly where the author lives in Scotland, but he has obviously been to the Hebrides many times, and I find the area fascinating to read about. The descriptions of nature taking back the land after most of humanity dies off are so vibrant that you really feel like you’re almost there.
Fletcher takes us back and forth between the time when The Gelding is announced and almost two hundred years in the future. Both focus on a male and female who are very close to one another, but the former is a couple who have become extremely interesting to scientists studying why almost no one is able to conceive. The latter two individuals are a few years apart in age, but they share more of a mother/sister and son/brother relationship, where it would be very weird to change that dynamic.
200 years into the future, Cat and Mouse live a very primitive lifestyle, just the two of them. She saved Mouse by carrying him away from the sea when he was extremely young and she was about six years old, and Mouse has never seen another human being other than Cat herself. Due to their isolation, Mouse’s narrative is different from what we would typically read. His words are more of a stream of consciousness, which may not sit well with some readers. I never had a problem with it, since I’ve read other books with similar styles. I am of the opinion that if you can get through and even love Patrick Ness’ “Chaos Walking” trilogy, as I did, this book is child’s play.
I will say that I found the later narrative to be much more compelling than the earlier one. That’s almost certainly because I happen to love post-apocalyptic stories more than ones set in our current time. However, I enjoyed both perspectives and was sad when the book ended.
If you liked “A Boy and His Dog at the End of the World”, you’ll almost definitely like this companion novel. This one *can* be read without reading the former, but I do recommend reading it first anyway, since the author has thrown a few things into this later novel that readers of both will be pleased to catch.
4.5 stars, rounded up.
As always, my sincere thanks to Orbit Books and NetGalley for an advance copy. All opinions are my own.

I read and loved A Boy and His Dog at the End of the World years ago, and since reading that I also read C. A. Fletcher's foray into horror, which I also loved. Then I didn't hear anything from him for a few years. After a recent move, I found that original bright orange cover ,put it on my bookshelf, and wondered what that guy was up to these days. Lo and behold, he had a new book coming out. Set in the same world as the original. And available for request on Netgalley.
Obviously, I requested it. Luckily, I received it. And also obviously, I loved it. This book takes the slow pacing of A Boy and His Dog at the End of the World and slows it down even more. This is a VERY slow burn. Fletcher's first-POV character, a young boy named Mouse, has so little experience with human interaction, aside from a girl, Cat, who has been with him since he was a baby, that he narrates mainly in streams of consciousness and similes. It definitely does take some getting used to, but once I got into the flow of the story, the prose struck me as incredibly beautiful. Fletcher perfectly describes the sheer isolation, the ever-present danger, and the ebb and flow of hope and despair that come from living in a post-apocalyptic world. There are few characters, but Fletcher uses them all to incredible emotional advantage. There is another timeline, concerning a young couple living through the original end-of-time some 200 years before Cat and Mouse's timeline. It was interesting to see a first-hand perspective of the Gelding, but honestly I just wanted more Cat and Mouse. The last 10% or so of this novel had me in tears. Fletcher brings everything together beautifully in the end with some heavy themes and emotional punches. I'm actually in awe of the masterful writing style here. I feel so privileged to have read this beautiful novel.

I started C.A. Fletcher’s The Two of Us at the End of the World with my coffee one morning, and somewhere along the way I realized this was going to be much more emotional than I expected from an end-of-the-world story. Thank you to Orbit Books for the gifted copy. What would it feel like if one person really was your entire world?
⭐️⭐️⭐️⭐️
Nearly two hundred years after humanity began disappearing, Mouse has only ever known Cat. She carried him away from the sea when he was little, kept him alive, taught him how to survive, and together they’ve built a life in a world where nature has reclaimed almost everything.
Then other people appear.
I loved Cat and Mouse together. Mouse especially got to me because he has such a different understanding of the world. Things we consider completely ordinary are strange discoveries to him, and seeing the remnants of our civilization through his eyes made this post-apocalyptic world feel incredibly real.
The story also takes us back almost two hundred years to a young couple falling in love while humanity is beginning to understand that something is terribly wrong. When they discover they may be among the few people still able to have a child, their very personal relationship suddenly becomes something much bigger.
I’ll admit I was always a little reluctant to leave Cat and Mouse when the story switched timelines. Their chapters were the ones I connected with most, and this is definitely a story that takes its time. But once the connections between the two timelines started revealing themselves, I understood why both stories needed to be there.
And that last part of the book? That’s where Fletcher got me.
For a story about humanity disappearing, this is surprisingly focused on what makes us human in the first place—family, love, sacrifice, connection, and the stubborn little bit of hope we hang onto even when the world looks pretty bleak.
I finished this one thinking less about the end of the world and more about the people we would fight to keep beside us.
What book has surprised you by being far more emotional than you expected?

The Two of Us at the End of the World is a profoundly moving exploration of what makes life worth preserving when civilization crumbles, anchored by intimate character connections that transcend the apocalyptic framework. The central question, what if one person was your whole world, reverberates through both timelines, grounding the narrative in emotional truth rather than allowing it to become mere survival spectacle. Mouse and Cat's relationship carries quiet devastation; watching their insular world fracture when strangers arrive creates genuine tension rooted in the fear of losing everything you've ever known. The parallel narrative spanning two centuries allows the author to explore how love, family, and human connection manifest differently across time while remaining fundamentally unchanged. The couple discovering their biological significance to humanity's future carries weight without becoming heavy-handed; their struggle against authority mirrors Mouse and Cat's struggle against isolation in ways that deepen both storylines. What distinguishes this work is its refusal to equate survival with victory; the narrative consistently asks whether survival alone justifies existence or if connection, creativity, and love elevate life beyond mere continuation. The prose moves with careful restraint, trusting readers to understand the weight of moments without excessive explanation. The character work is particularly strong; even minor figures feel purposeful, and the four unforgettable characters promised in the description each earn their presence through genuine emotional arcs. However, the pacing occasionally stumbles when switching between timelines, requiring readers to recalibrate emotional expectations with each shift. Some readers may find the ending's ambiguity regarding hope unsatisfying if they anticipate conventional resolution rather than thematic completion. Despite these minor considerations, this is a haunting, deeply humane story about resilience that refuses to diminish its characters' inner lives in service of external plot machinery.

Thank you to Netgalley for the ARC.
Both The Two of of Us at the End of the World and A Boy and His Dog at the End of the World work great as standalone books, but I think that the combination of the two does a lot for the world building and atmospheric feel of the books, giving the reader a fuller scope. While A Boy and His Dog has a much bigger scope of bringing home a piece of your family when separated, The Two of Us has the opposite approach of trying to hold onto your family that you've built for as long as you can, staying right where you are. The children of this world are strong and resourceful and have been shaped by their surroundings beautifully, which while sometimes I found myself thinking "could a kid this age actually do this" I generally resolved it very quickly of "well, of course, this is the only world they know". The world is harsh and dark, but Cat and Mouse fill their lives full of love the best that they can.
I really like the deep dive into the Beginning of AG that we got to experience even for a short time, because while it covers a short period, it was very realistic in the decline of society and what would have probably happened in our current ecosystem.
Very well done - if you liked A Boy and His Dog, you'll like this dive back into the same world. Similar trigger warnings for both books

4.25 stars.
Infertility is rife, the population is rapidly falling, and pandemics are the norm. We follow two timelines; a couple who have just lost a pregnancy early into the time everything changes, and a boy and girl two hundred years in the future, struggling to survive.
This was very compelling, one of those books where I couldn't put it down. I do have to say that I much preferred the future storyline, and when the story switched to the young couple I was desperate to be back with Cat and Mouse (the boy and girl). However I can see the benefit of seeing both stories.
I really liked the isolated world this book creates, and the ingenuity of Mouse and Cat as they make a home for themselves, and even welcome others.
One thing that did bother me after a while was the constant heavy foreshadowing. The future parts are narrated by Mouse, and the chapters regularly end with something along the lines of 'if only I'd known things were about to change'. I just wanted the story to flow naturally, and I didn't like the interruptions reminding us how difficult things are going to get.
The emotional moments here really hit hard, and I was invested in the characters. If a book has those two things it's always going to be a winner for me. A very solid post-apocalyptic book.

Disappointed. Unlike the first book, A Boy and His Dog at the End of the World, this second iteration of CA Fletcher's post-apocalyptic world gave me no one I could relate to or feel any strong empathy for and was missing "the mission" from the first book. Every part of my dog-loving soul understood what was driving Griz in book 1 to take on crazy challenges in pursuit of the stolen Jess. Book 2 gives us all the same gut-wrenching nightmares with wild animals, horrible people, disease, but there is nothing that explains why our protagonist puts himself through it. And to add to my nonplussed reaction, Mouse is so in his head and odd that I just couldn't relate. Would a kid who grows up with no adults and only one other human be odd - yeah, probably, but that doesn't mean I'd like him or relate to him and I didn't. The only character I did like was the dog who really only has a bit part in this book unlike the book 1 where the dogs were driving much of the story. There is a lot of action and tension in the books, but when you don't much care about the outcome, it becomes repetitive and a bit tiresome. There is some engaging writing, a lot of creative energy, and good narration which took me to the end, but this one was not for me. If you really love dystopian bleak stories and care more about action than characters, you might enjoy it more than I did.

The Two of Us at the End of the World by C. A. Fletcher
Thank you to Orbit Books for providing me direct access to this ARC through NetGalley in exchange for my honest review.
The Two of Us at the End of the World returns to the world of A Boy and His Dog at the End of the World with a new story told across two timelines.
Nearly 200 years apart, we follow four characters. In one timeline, a boy and a girl experience humanity's decline following G-Day, when humanity becomes infertile and sickness begins killing off the population. In the other, Cat and Mouse have grown up in the nearly empty world left behind.
The two stories seem impossibly separated.
The question is: How is Fletcher going to connect them?
📖 Storytelling - 4.0
I absolutely loved A Boy and His Dog at the End of the World. It was one of my biggest surprises of 2025, so when I heard C. A. Fletcher was returning to this world, I knew I had to get my hands on it.
This time, Fletcher uses a dual-timeline structure, and in my experience, it's one of the easier ones to manage.
In one timeline, we watch a boy and girl living through humanity's decline. In the other, nearly 200 years later, we follow Cat and Mouse as they try to survive in the world humanity left behind.
Immediately, there's one big question hanging over everything:
How is Fletcher going to connect these two stories?
Along the way, we learn more about G-Day, the moment humanity's collapse truly begins. People stop being fertile, while sickness starts killing off the population that remains. It's not one giant catastrophic event. It's a slow, terrifying unraveling of the future itself.
That idea remains just as haunting the second time around.
At its heart, though, this becomes another story about young people trying to survive in a world that feels almost completely empty.
Except Cat and Mouse are about to learn something very important.
It isn't.
👥 Character Work - 4.0
Our story focuses on four characters.
In the earlier timeline, we have simply the boy and the girl. We never even learn their names, but as their story unfolds, we begin to understand the tragedies that have been set upon them as they watch the world around them slowly disappear.
Then, nearly 200 years later, we have Cat and Mouse.
These were easily the characters I connected with most.
Cat and Mouse travel together, hunt together, and have learned how to survive in a world where other people are almost nonexistent. Mouse calls Cat his entire world because, without her, he wouldn't have survived.
And their personalities balance each other beautifully.
Cat is cautious. Mouse is curious.
Somehow, the two of them make it work.
We spend the majority of the book with Cat and Mouse, and I definitely preferred their chapters. Their relationship gives the story its heart, especially once they begin discovering that some of the things they believed about their world might not be entirely true.
But if you've read A Boy and His Dog at the End of the World, you already know something about C. A. Fletcher:
He always has something up his sleeve.

⏱️ Pacing - 4.0
If you're looking for a fast-paced story that you're going to burn through in a couple of sittings, The Two of Us at the End of the World might not be the book for you.
This is definitely a slow burn.
Fletcher takes his time revealing the truths about this world and, more importantly, the people who still inhabit it. There were a few chapters where I could feel the story slowing down, particularly when I wanted answers to some of the bigger questions Fletcher had planted.
But those answers are more than rewarding.
Part of what kept me going was simply how much I already love this world. After A Boy and His Dog at the End of the World, I knew better than to assume Fletcher was showing me everything. There's always something else happening underneath the surface.
And then you reach that final 10%.
Good luck putting it down.
All of those slow reveals start coming together, questions begin getting answers, and suddenly the deliberate pacing of the earlier chapters makes sense. I went from patiently following the story to needing to know how Fletcher was going to land it.
This isn't a book that races toward its ending.
It earns it.
✍️ Prose & Style - 4.0
I won't lie, it took me a chapter or two to get back into Fletcher's style of storytelling.
But once I did, I remembered exactly what worked for me the first time.
Fletcher has a way with words that makes you feel the loneliness of this world. Nearly 200 years removed from the society we recognize, Cat and Mouse don't understand everything the way we do. The way they speak, explore, and interpret the remains of the past reflects the completely different world that raised them.
And some of my favorite moments were the smallest ones.
Discovering that people used to bury their dead instead of simply burning them. Finding a copy of First Aid for Dummies and using it to learn how to treat cuts and wounds. Ordinary pieces of our world become strange artifacts to people who have no connection to the society that created them.
It's beautifully done.
But Fletcher is also constantly hiding things just beneath the surface. A word choice, an observation, or some seemingly insignificant detail might mean considerably more than you initially realize. If you're truly paying attention, there are pieces waiting for you to find them before Fletcher finally reveals what's going on.
That makes this a style of storytelling you have to settle into, but it's incredibly rewarding when you do.
I will also mention that this story handles some sensitive and potentially difficult subjects, so I'd recommend checking the trigger warnings before picking it up.
❤️ Emotional Impact - 5.0
There are times when you finish a book and immediately reach for whatever is next on your shelves.
This was not one of those times.
I finished The Two of Us at the End of the World and just sat quietly in my chair for a good ten minutes before I even turned off my Kindle.
I needed a minute.
That's probably the best compliment I can give this book. I went into it with expectations that were probably unfairly high because of how much I loved A Boy and His Dog at the End of the World. Fletcher had to live up to the hype I'd built entirely in my own head.
And somehow, he did.
By the time everything comes together, the slow burn, the two timelines, Cat and Mouse, the boy and the girl, and all those little truths Fletcher has been hiding beneath the surface suddenly carry so much more weight.
If you haven't read these books, I definitely think you should. Fletcher says they can be read independently and in either order, but personally, I'd recommend starting with A Boy and His Dog at the End of the World. I think knowing this world beforehand makes returning to it here even more rewarding.

Not every book that sticks with me earns five stars.
Sometimes a book can have slower chapters, characters I connect with more than others, or a style that takes me a little while to settle into and still absolutely nail the one thing that matters most when I close it:
It made me feel something.
The Two of Us at the End of the World did exactly that.
C. A. Fletcher brought me back to a world I already loved, showed me another corner of it, and then reminded me why A Boy and His Dog at the End of the World surprised me so much in the first place.
When I finished, I didn't grab my next book.
I just sat there.
Sometimes that's worth more than the number of stars at the bottom of a review.
Thank you to Orbit Books for providing me direct access to this ARC through NetGalley in exchange for my honest review.
The Two of Us at the End of the World returns to the world of A Boy and His Dog at the End of the World with a new story told across two timelines.
Nearly 200 years apart, we follow four characters. In one timeline, a boy and a girl experience humanity's decline following G-Day, when humanity becomes infertile and sickness begins killing off the population. In the other, Cat and Mouse have grown up in the nearly empty world left behind.
The two stories seem impossibly separated.
The question is: How is Fletcher going to connect them?
📖 Storytelling - 4.0
I absolutely loved A Boy and His Dog at the End of the World. It was one of my biggest surprises of 2025, so when I heard C. A. Fletcher was returning to this world, I knew I had to get my hands on it.
This time, Fletcher uses a dual-timeline structure, and in my experience, it's one of the easier ones to manage.
In one timeline, we watch a boy and girl living through humanity's decline. In the other, nearly 200 years later, we follow Cat and Mouse as they try to survive in the world humanity left behind.
Immediately, there's one big question hanging over everything:
How is Fletcher going to connect these two stories?
Along the way, we learn more about G-Day, the moment humanity's collapse truly begins. People stop being fertile, while sickness starts killing off the population that remains. It's not one giant catastrophic event. It's a slow, terrifying unraveling of the future itself.
That idea remains just as haunting the second time around.
At its heart, though, this becomes another story about young people trying to survive in a world that feels almost completely empty.
Except Cat and Mouse are about to learn something very important.
It isn't.
👥 Character Work - 4.0
Our story focuses on four characters.
In the earlier timeline, we have simply the boy and the girl. We never even learn their names, but as their story unfolds, we begin to understand the tragedies that have been set upon them as they watch the world around them slowly disappear.
Then, nearly 200 years later, we have Cat and Mouse.
These were easily the characters I connected with most.
Cat and Mouse travel together, hunt together, and have learned how to survive in a world where other people are almost nonexistent. Mouse calls Cat his entire world because, without her, he wouldn't have survived.
And their personalities balance each other beautifully.
Cat is cautious. Mouse is curious.
Somehow, the two of them make it work.
We spend the majority of the book with Cat and Mouse, and I definitely preferred their chapters. Their relationship gives the story its heart, especially once they begin discovering that some of the things they believed about their world might not be entirely true.
But if you've read A Boy and His Dog at the End of the World, you already know something about C. A. Fletcher:
He always has something up his sleeve.
And eventually, those four characters and two timelines have to lead somewhere.

Review of advance copy received from NetGalley
Thank you to Orbit and NetGalley for the advanced copy.
This book features parallel perspectives that are separated by several hundred years. One tells the tale of the world's slow destruction through the eyes of an unnamed protagonist. Juxtaposed is a story set farther in the future that focuses on the long-term impact of societal decline. In it, two young people, Cat and Mouse, find themselves alone together in a vacant world that is returning to nature.
Overall, this was a gripping dystopian tale that leans more toward a bleak future rather than an overtly hopeful one. With significant interiority, the characters explore what it means to be alone, what makes a family, and how to survive when there is almost nothing left.
Note: C.A. Fletcher has another similarly titled novel; however, I read this as a standalone and do not feel as though I was missing any significant information or elements from earlier in the series.

I Loved the Two of Us at a the End of the World. Unlike most dystopian novels, its appeal isn’t in the drama of survival and the fight for resources. Rather, it is a hauntingly quiet story, focussed on human connection when most of humanity is gone.
The story is told in alternating time points, the first following the immediate aftermath of the destruction of humanity, and the second centuries when isolation is the way of life. I loved the juxtaposition of the narrative style - the girl and the boy having experienced the world before, and cat and mouse having only the knowledge they have gleaned secondhand.
The reading experience reminded me a bit of Station Eleven by Emily St John Mandel, one of my favourite books. Amidst the loss and hardship, the overarching themes were those of humanity, connection, love, and ultimately hope.
Thank you to the publisher for an advance copy of this book via NetGalley. Opinions expressed are my own.

Review of advance copy received from NetGalley
This book is told in dual timelines, one right after people discover the world population discovers it is in decline. That genetically, there will be no more babies.
The second timeline is about two hundred years later. Mouse's point of view is quite different than a conventional narrative. It is sometimes disjointed and seems build to a tension that almost doesn't pay off. There is this underlying frenzy and fear in the narrative, when Mouse outwardly seems calm and very methodical.
Almost until the very end I wasn't sure about the narrative, or about Mouse's storyline. But the payoff at the end made everything make sense, and it all worthwhile.
The unconventional narrative definitely pays off.

Review of advance copy received from NetGalley
I loved A Boy And His Dog At The End Of The World, so I was happy to see CA Fletcher returning to that setup. You don’t need to have read the previous book to enjoy this one, but there are connections you’ll enjoy if you have. It’s a highly readable story of survival in a world where all of our modern ways of life have been ripped away, along with most of the people, interspersed with a smaller, sadder story illustrating how it got to be that way. You’ll care or the characters and root for them to overcome the perils they face. There are a couple of plot threads left dangling at the end, and I’d be very happy if there was to be another book in the series. It’s the sort of thing I could imagine John Wyndham writing if he was working in today’s world.

I kept thinking of Piranesi while reading this, mostly from that innocent voice of Mouse describing daily routines in a world that has already fallen apart.
The story moves between two timelines, but they remained easy to follow because each one felt like its own separate world. Mouse and Cat’s story has more of a coming-of-age feeling, with daily life unfolding among ruins that have been there for generations. The Boy and the Girl’s story is a love story, shaped by the difficulty of having children in a world already starting to crumble.
It is slower moving at times, with quiet stretches of daily life before the larger events break through.

Loved it as much as the prequel
I really loved The Boy and his Dog at the end of the world and completely missed this sequel being published. I
discover it when watching a Instagram post of dystopian books not to be missed so I grabbed a copy.
I’m immediately enthralled in the story and want to know more about the characters
There are 2 time periods in the story which continues the story of the universe of the previous novel the first time period is l just after the world changed and women stopped being able to get pregnant and the second is 200 years later
In the first we meet a boy and girl who seem to be one of the last couples to get pregnant and in the second a boy and girl living an isolated life after most people have died .
I loved the description of the birth as a paediatrician I’ve attended hundreds of births and this one was very realistic primal messy and perfectly described
The author has a very clear easily red flowing writing style and this book was an absolute joy to Read. I really loved it.
This review would appear on Goodreads StoryGraph, and my book blog bionic Sarahsbooks.wordpress.com. It will also appear on Amazon UK.

(5 Stars)
I need to be honest, on a scale of 1-5, I'd rate this a 10 if I could. I loved this book. And the audiobook was narrated by the author, which was a nice touch.
This author is excellent at writing engaging characters, ones that you get invested in, and ones that you care about what happens to them. I was on the edge of my seat for most of this book, and I was getting emotional while reading it. I think I literally (and quite vocally) gasped more than a few times.
Do yourself a favor and read this, and every book by C.A. Fletcher!

Like A Boy and His Dog At The End of the World, this one is two young people at the end of the world.
And later, a dog.
Told in two timelines, 11 years after the Event (AG) and 201 years after. Mostly 201 years after.
It starts quietly, their life alone, as the world is slowly returned to plants and wildlife and then...
It's not without drama at this stage though.
At around 74% the OMG action parts start and it's nail biting until the end.
Highly recommended.

Spectacular story. I loved the previous A BOY AND HIS DOG AT THE END OF THE UNIVERSE and was hope this new one would be a good. It exceeded my hope. While both books are in the same world, they are not connected (but a clever reference of the first in the second made me smile). I loved the two timeline format. I loved the narrators, especially Mouse, although at times his comments kept me on tenderhooks, which only added to the greatness of the story. THE TWO OF US has joy and sadness and hope. Highly recommend.
October 1, 2026
Definitely read A Boy and His Dog at the End of the World before you read this. They beautifully and ably bookend each other.
I just finished this one and would love to be able to entirely forget both books so I can read them again like they’re new. Instead I’ve set a date for next year to do so. In the meantime I’ll have to live a little vicariously through recommending these to my friends and enjoying their responses.
Thank you Charlie.

This author WEAPONIZES foreshadowing, in the best possible way. Talk about DREAD, hoooo wheeee this played with my emotions. There's a lot to unpack here and a lot to think about. Of the 2 story lines, Cat/Mouse connected much more than Boy/Girl. If you've read "A Boy and His Dog at the End of the World" you will have a big "A ha!' moment. This was just a great propulsive read, with engaging characters and a Very Special Dog. Who could ask for more than that?
August 2, 2026
Complex characters in an interesting world. This story definitely sucks you in, the writing just grabbed my attention and held on. One of my favorite reads so far this year. There were some parts that were predictable and others I never saw coming, same as the characters in the book. I wish there was more.
September 20, 2026
I am biased toward C.A. Fletcher. I freely admit that. A Boy and His Dog at the End Of the World was my absolute favorite read a few years ago.
I think this new book, The Two of us At the End of the World is better. Six stars!
His descriptions throughout the book kept enticing me to verbally acknowledge their brilliance.
I sure hopes he writes the next one soon

I loved this book. It was heart breaking and yet life affirming. I really enjoyed the character building and was the rawness of Mouses innocence and his perspective was particularly moving.

I don't know what to think about this book. I didn't love it or hate it But just thought "so what"

This book should be a movie. But the book will always be better! Detail, imagination, descriptions are so well done.

September 11, 2026Excellent! As well as his others! I only wish the story was longer! Loved it!!!
Did Not Finish
September 19, 2026I was very much enjoying this book until a character got raging post-partum depression and committed child abuse. NOPE.
