Our Infinite and Inevitable Ends

by A.D. Sui

This sapphic cli-fi thriller is a love letter to hope in the bleakest of times, combining the multiverse-bending drama of This Is How You Lose the Time War with the cat-and-mouse chase of Killing Eve.

On a near-future Earth devastated by climate change, Dr. Cassandra Barlowe is right where she wants to be: working on an island of floating trash in the middle of the Pacific Ocean, as far away from Dr. Yana Gulsvig as possible. Cas’s research on plastic-dissolving fungi is undervalued and underfunded, thanks to the invention of deleria, a drug that allows glimpses into different timelines. For the average user, it’s a way to view lost loved ones or experience a different life, but it also offers a glimpse into worlds where humanity has solved its many global crises. Now, most science funding is dedicated to trawling these different timelines, searching for a reality with the solution to the climate devastation.

But when Yana — the world’s leading expert on deleria and Cassandra’s ex-lover — is killed in a mysterious explosion in the hub of deleria research, taking the hope of reversing climate change with her, Cas is arrested on charges of domestic terrorism. Cas must delve through timelines to piece together what happened, while watching other versions of herself and Yana live out the life they could have had — happier, more in love. As brutal government agents close in and her addiction to deleria grows, Cas has to make a choice: live in the spiraling branches of reality, seeking closure for Yana’s death until the drug shatters her mind, or live in the now, even if that means embracing her own damaged self and fighting, however hopelessly, for her own future and that of humanity.

Review of advance copy received from NetGalley.


If climate and psychedelics speak to you, then this one’s for you!

Science enthusiasts will be delighted as well. The science in this book revolves mostly around neuroscience. It’s all really digestible, of course, nothing too complicated.

I was so hooked by this book to about 70%, then the end fell flat for me. It dragged for too long and I don’t think I fully grasp everything. I still think it’s a really good book to read as the topics and story are so compelling. I definitely don’t feel like I wasted my time reading this book and would still recommend it highly! Cli-si/sci-fi has a way to my heart, so I might be a little biased. I was sold by the premise and the book did not disappoint on that end.

In this futuristic bleak, gloomy world at the mercy of climate change where acid rain is a constant that threatens to be nonstop, we follow our main character Cass, working on the Patch (Island of trash in the Pacific Ocean). As she receives the last call from her ex Yana, she’s then dragged back to Toronto with potential charges of complicit terrorist attack in destroying TempCog, the academic provider of Revelation, a drug allowing people to see other realities and the biggest hope for the resolution of the climate crisis. As Cass doesn’t believe in the suicide of the dearest person to her, she’ll start her investigation to know what happened.

Chapters are a really good length, which I really love, not too long, not too short, and the writing style is really efficient. All the characters are well developed. We’re fast immersed in the story. For example, even though we know so little of Cass and Yana’s story at the beginning, I could feel every ounce of emotion Cass was living after she received the call. I was as numb and devastated as her. I was therefore invested from the beginning, not only by the unusual place she was living in or the strong action kick-off, but by my feelings for the character and her past life that I don’t even know of.

The relationships are a bit weird in this book bordering on obsession, but that didn’t bother me. Overall it was believable and understandable. Having all female characters was intriguing and refreshing. I also liked the duality between Cass and Yana. We have Cass who is seeing the bad side of corp. and the impending doom looming over humanity. She’s also nonchalant over social norms and the pursuit of greatness. And then we have Yana who’s optimistic, passionate, has high standards and is charismatic.

Cimate awareness is big in this book. I was constantly reminding myself how lucky we are that our planet is still fairly in good condition. Obviously and unfortunately we are rapidly going towards a semblance of this world. It’s so sad to think that we will lose what we take for granted right now. Of course, I already knew, and do my best to have good habits for our planet, but that book made it so much more real in my head and is a good wake up call to have our utmost awareness towards what’s happening right now and what we can do.

Some of the critics/comments I have are the following :

- It’s always raining, people are never seeing the sun, in Toronto at least. It must take a toll on mental health, but people seem to live normally. I would have liked more of a general description of population health. How does it affect people? What are they doing to cope with it? I know Maya in this book represents the hopeless young generation and we can understand more through her, but I would have liked to have a better understanding still.
- I’m not sure I understand the ending fully. Can someone explain to me how Yana knew everything before the end?
- Really strong start and maintained during most of the book with everything new we learn, but a lingering ending. Could cut down at the end and make things clearer, concise. Make it make more sense. I really liked the message about the climate crisis though.
- Did the government agree on the destruction of the map? All this for nothing… Could be conserved and locked away. And surely it is stored elsewhere.

The concept of this book has so much potential! I do think that it could be reworked to become even better. As read in another review, with the good editing, I think this book could go very far.

I will definitely be reading other books by this author as I really liked her writing style, concepts and imagination.

[Sian · Rating 3 out of 5]

Our Infinite and Inevitable Ends presents an intriguing and timely premise — a futuristic vision of what our world might become if the climate crisis continues unchecked. The novel explores humanity’s tendency to search for perfect solutions in alternate realities rather than confronting the flawed but meaningful lives and relationships right in front of us. Conceptually, this was one of the book’s strongest elements, and it immediately captured my interest.

I appreciated that the story centres predominantly on female characters, which felt refreshing. However, I struggled to fully connect with them. Unlikeable characters can absolutely work when their motivations feel clear and emotionally grounded, but here that depth sometimes felt missing. Cassandra, in particular, came across as somewhat shallow and impulsive, and her love for Yana felt closer to obsession than romance, largely because we are given very little insight into how their relationship actually developed. Maya also leaned heavily into the moody teenager stereotype, despite hints that she was intelligent and witty enough to have been portrayed with more nuance.

The writing style itself is strong and often engaging. That said, parts of the opening leaned heavily into exposition, reading almost like a science textbook as the narrative explained the world’s history and technological background. I found myself wishing the worldbuilding had been revealed more organically through character experience and discovery rather than direct explanation.

Overall, I enjoyed the ambition and ideas behind this novel, but it ultimately missed the mark for me in terms of character development and immersive worldbuilding. A compelling concept and thoughtful themes made it an interesting read, even if it didn’t fully realise its potential.

Thank you to NetGalley and the publisher for providing an advance copy in exchange for an honest review.

Sui is now on my autobuy list after this, The Iron Garden Sutra, and the Dragonfly Gambit. Just go and preorder this now. The two things you need to know about this book going in: 1. There is a drug that allows you to see into alternate universes. 2. Dr. Cassandra Barlowe is working on a plastic eating fungi on the Great Garbage Patch, and Dr. Yana Guslvig is the leading researcher on the aforementioned drug, and they used to be with each other. The story kicks off with Cassandra finding out Yana has died in a suspicious matter, and the novella is her journey using the drug to try and find out what actually happened, while also tormenting herself with other visions of herself and Yana in other timelines, with government agents thrown in as a fun side quest to deal with throughout this. Throw in the fun existential question of "should we invest money in actual practical proposals vs looking to other realities for what their solutions were or weren't", and deciding how to live your life after a major grief inflection point, and you have a hell of a novella. Highly recommended.

A heartwrenching tale of love and loss in a dystopian setting. One of the most unique and compelling parallel reality stories I've read! (Plus I'm a sucker for a great story set in Toronto!)

got the arc for this just after finishing a nonfiction book about the climate crisis for my book club. could not have been better timing & really enhanced my reading experience!! full rtc

[payton · Rating 3 out of 5]

I fear this is going to be a DNF book for me. The concept is fascinating and there’s SO much potential to write a haunting story on grief, climate/environmental dissonance, and identity, but I just don’t feel emotionally connected to these characters.
There are several details in this book that are inconsistent or don’t make sense, such as :

- Cassandra’s decision to put a six month’s down payment on an apartment, then abandon it weeks later, but she never bothers to spend the money for a lawyer or try to get free legal aid

- how long Yana and Cassandra knew each other (is it 20 years? 30?) and how they met

- Why the Canadian Intelligence Agency (or at least Cromwell) is a despicable/villainous organization in this book

- Cassandra being an orphan - it’s barely referenced in the first bit of the novel, then suddenly is mentioned so frequently with details of CSA and physical abuse. This really threw me off more than anything because it never had an exposition.

Also, I’m all for writing problematic or unlikable no characters (especially when they’re queer women), but I truly cannot understand Cassandra, and the novel doesn’t work to even neutrally justify some of her actions and thinking with her grief. There were several times where—maybe because the depth of her emotional connection to Yana wasn’t convincing—she came off as an ex who, after six years, needed to move on and stop being jealous. She’s grieving a 20-year relationship that was highly toxic and never became something official, so it makes sense her thinking will be irrational, but she isn’t written as being in an irrational frame of mind. Most of her grief around Yana is expressed through anger and jealousy at the situation and others who were close with Yana—I didn’t think there was enough focus on the sheer grief, especially that she’d feel when seeing her in a parallel reality. This makes it difficult to sympathize with her, even though she should be a sympathetic character.

Finally, the pacing, while interesting, is a bit slow, and the book struggles with some sudden transitions and over explaining/stating the obvious. It seems like the author wanted to include research they did in the book, but things like dissociation or a psychedelic drug class should be common knowledge, if not at least inferable.
I think delving further into the world building of this book as it relates to the climate crisis and creating specific scenes grappling with the loss of environment and cultural ways would be far more impactful than what feels like some blanket statements on the Fridays for Future movement. The book could explore what’s happening in other countries, especially the ones suffering most from climate change; how Canada/other countries countries contributed or responded to the crisis (could reference UN system and multilateral agreements here); and how the environmental conditions of the novel happened or when. While Yana and Cassandra are psychologists by training, both of their work, especially Cassandra’s on the patch, is directly in support of climate solutions. As brilliant women and through their work, they would realistically know far more about different aspects of the environmental field than is currently written, and this should be reflected in their decisions and worldviews, not directly stated as fact.

I do think this novel is a critical one to write, and I love the premise of a scientist trying to solve the mystery of her ex-lover’s death using alternate realities in a world plunged into the climate crisis. It’s unique, and fascinating, and has SO much potential for multifaceted, relatable characters and highly emotional moments. It could be that this writing style just wasn’t for me, but I do think with the right editing this kind of plot and concept could truly make for a breakout book.

[Georgia · Rating 5 out of 5]

ARC Review: I was not entirely sure what to expect from this book, however, I ended up really enjoying it. This is a solid 4.5 stars for me (rounded up).

First off, the writing style is gorgeous. It leans more towards prose than simple writing, it's almost lyrical at times, but never to the point where it feels overwhelming. It’s the kind of writing you want to slow down and appreciate while still being pulled forward by the story. Speaking of that, the pacing is impressively well done. There really aren’t any lulls and something is always moving whether it’s plot, character development, or emotional stakes. It kept me consistently engaged without ever feeling rushed. One thing I especially appreciated was how the book handled its more scientific language. Whenever things got a bit dense, there was always some kind of explanation or a more digestible “for example” moment right after. It made the concepts easy to follow without dumbing anything down, which is a tricky balance and was executed really well here. Obsession runs quietly but powerfully through Our Infinite and Inevitable Ends, shaping both the characters’ choices and the emotional weight of the story. It’s not just destructive, it’s the very thing that keeps Cassandra going when giving up would be easier. The structure also worked in its favour. Chapters are nicely spaced and not overly long which made it super easy to keep reading “just one more” (and then five more after that). The characters is where I feel this book shines. Even the side characters who only appear briefly (Maya, Lori, Garcia) feel fully formed. No one comes across as flat or surface-level, and importantly, none of them felt irritating or unnecessary. That alone made the book feel richer and more immersive.

If I had to offer a small critique, it would be that the writing, while beautiful, occasionally borders on slightly too dense in certain passages, which might slow things down for readers who prefer a more straightforward style. It didn’t take away from my enjoyment much, but it’s worth noting.

Overall, this was a thoughtful, well-crafted read with strong writing, engaging pacing, and deeply developed characters. Definitely one I’d recommend if you enjoy an emotional story of love and obsession, deep inner thoughts of characters, and substance to the plot.

Im just gonna leave these quotes I loved down here... (no spoilers)
"Part of me always wonders how much of the wold i polluted by just being myself."
"I'm Cassandra and I pray at a church pew to a God I've forsaken. I remember those words. I remember their cadence. They flow from me like a river breaking from a dam."
"I'm letting you go so the world may survive"

Our Infinite and Inevitable Ends is a swirling and captivating story about what happens to science when we're past the climate change point of no return. Dr. Cassandra Barlowe - who once had hopes and dreams of being the climate scientist who would fix it all - finds herself spiraling into drug addiction after her ex-girlfriend Yana dies in a mysterious explosion at a Toronto research institute. Cassandra's addiction? To a drug called deleria, which allows the user to see into alternate realities. The explosion? To the very facility that deleria was most heavily being researched at. Cassandra finds herself digging deeper and deeper into why and how Yana was involved in the explosion, deleria research, and the undoing of the climate crisis itself.

This book is very interesting and reminded me so much of one of my favorite pieces of media of all time, the show Orphan Black. I think - just like with OB - it can be so frustrating to have an unreliable narrator drive the story. We watch Cas repeatedly make stupid decisions over and over again as she spirals deeper into deleria, hurting those around her as she chases the answers that aren't there. It's one of those things that as a reader is so frustrating but also completely understandable from a storytelling perspective. (that doesn't mean I have to like it, lol)

I think this is an overall really good book, that was sometimes a bit confusing, as there would be timeskips that wouldn't be clearly communicated (for example, a 3 month time skip happens within a chapter indicated only by a few line breaks) or certain dislocated associations (Cas talking about one thing, making a conclusion about it, then quickly pivoting to a completely different topic) that took re-reading a few times. But the story itself is very fascinating and I would certainly recommend it to anyone who is wanting a book that tackles a climate crisis future in a unique way.

3.75/5

[Rose · Rating 2 out of 5]

There’s lots of potential here in terms of the concept and the blurb comparing it to This Is How You Lose the Time War had my attention. Unfortunately, beyond the theme of alternative realities, there are few similarities and the writing itself isn’t very good.

There are cliches like characters stomping their foot in anger (which I’ve never seen someone do irl). There’s a lot of repetition and over-explanation of certain things while others remain weirdly underdeveloped. We are constantly told how close Cass and Yana were but without actually seeing this it’s challenging to feel invested.

I didn’t like the excessive use of therapy speak, Cass was always perfectly aware of how her trauma shapes her relationships with others and it just all felt a bit artificial and unnatural. There are also inconsistencies like how initially there was a big focus on decontamination showers but this stops appearing after a while despite the mc constantly going in and out of buildings. And I never felt convinced as to why Cass had no choice but to take Deleria vs just doing a normal investigation without it.

Finally, I feel like as a story meant to illustrate the need to act imperfectly to reduce the harms of climate change vs waiting for a perfect solution to emerge, it didn’t really use the narrative to the fullest extent since the perfect solution never really felt credible. You end up at the same point at the end as you were at the beginning and it makes it feel like none of the plot itself mattered.

Thank you to NetGalley and the publisher for the eARC.

[TheNovelNomad · Rating 4 out of 5]

This sapphic cli-fi thriller is ambitious, emotionally charged, and quietly devastating in the way it blends love, grief, and climate anxiety into one layered narrative. It’s as much about what could have been as it is about what still might be, balancing speculative science with deeply personal stakes.

The multiverse element adds a haunting emotional dimension, allowing the story to explore alternate lives, missed chances, and lingering love. Watching different possibilities unfold creates a bittersweet tension that runs alongside the central mystery, giving the narrative both urgency and melancholy. The relationship at the heart of the story feels fractured yet magnetic, shaping every choice and every timeline.

The near-future setting is bleak but thoughtfully constructed, with climate collapse forming a constant backdrop. The scientific concepts—particularly the search for solutions across timelines—add intrigue while reinforcing the themes of hope, desperation, and humanity’s tendency to look elsewhere instead of fixing what’s in front of it.

There’s also a strong undercurrent of obsession and grief that drives the pacing forward. As the stakes escalate, the story becomes both a chase for truth and a struggle to remain grounded in reality. That tension between escape and acceptance gives the narrative emotional weight.

Inventive, atmospheric, and poignant, this is a compelling blend of speculative fiction and romance that explores love across possibilities while holding onto a fragile thread of hope.

thank you to NetGalley for an ARC of this book in exchange for a review.

"our infinite and inevitable ends" is a brain melting spiral into the consequences of perfectionism and compounding guilt. following the fall out of yana's death and the explosion of the TempCog building, cas chases a never ending thread of infinite realities to solve yana's death, clear her name, and save earth—if she can. stuck between visions of a life she's never lived, a cop desperate to close the case, and yana's maybe-ex-lover, cas struggles to reconcile what all she's left behind for good.

this book does many things well and above all else, the grace with which it depicts the often messy reality of loving another person and living on a dying planet is exceptional. lost somewhere between hope for the future and grief for the past, "our infinite and inevitable ends" asks the reader to take a leap of faith. the bone-deep sorrow the characters feel and express was so candid that i found it impossible to not be sucked in to their descent. the surrealist imagery of overlapping timelines, drug addled crash outs, and whispers from the past all coalesce into a downward spiral that cas goes on head first. it was an absolute delight to read and was addictive from the start with one of the most solid opening chapters i've ever read. thank you so much to NetGalley and A.

WOW!

A sapphic, acid rain soaked, cli-fi thriller of a devastated earth with a brain melting drug that lets you glimpse other possible realities, “Our Infinite and Inevitable Ends” feels like Bladerunner 2049 meets Blake Crouch meets This Is How You Lose the Time War. And it knocked my socks off!

Far away from her ex-lover, Dr Cassandra Barlowe is on a floating island of trash in the ocean researching plastic eating fungi to help better an Earth completely devastated by climate change. Research that is ridiculously underfunded due to the existence of a drug that gives the user glimpses into other possible realities.
But after leaving Cassandra a cryptic voicemail, her ex is killed in a mysterious explosion - taking vital research into reversing climate change with her. Cas has to turn to the reality bending drug to piece together the mystery of what happened.

Tumultuous relationships and beautiful writing come together in a novel I just couldn’t put down! Set in a future where climate change is past the point of return, this novel is heartbreaking and all too close to home in its messaging.
Breakneck pacing, unravelling mysteries and complicated love triangles had me up until 2am devouring this book as fast as I could - after this I will read absolutely anything and everything A.D.Sui writes now!

[Ridgerunner · Rating 5 out of 5]

What a blockbuster of a novel. Love , obsession and grief are the main themes concerning the three women at the centre of things in the near future when climate change has become serious. Novels dealing with time travel or alternative realities as here often become so complex that it feels impossible to keep track of events , but here it is reasonably understandable as the world looks for solutions to the climate crisis. Yana and Cass are the two scientists dealing with drug enabled alternative realities who have a volatile relationship and eventually part. Yana dies and Cass returns to try and find out what had happened. Cass becomes involved with Sandra , another brilliant scientist and I loved reading about their complex relationships as we find that all three are more connected than first appeared. Lots of introspection but it never is boring as we find out more and more about what makes them tick. Towards the end of the book as Cass’s brain becomes more damaged the narrative becomes almost dreamlike and the reader feels themself becoming part of this confused state. I was absolutely hooked on this book and it kept me thinking long after I had finished.

3.25/5✨

“When she fought everything else so wholeheartedly, why didn’t she fight for me to stay?”

I was so excited when I saw the premise of this book. Sapphic sci-fi thriller? Sign me up! While I overall enjoyed this, the execution fell a little flat for me.

There is no doubt that this author writes beautifully, but the inconsistent pacing and character motivations is what took away from the plot. At times, I feel that certain concepts are over-explained, but then others were glossed over. Additionally, I had a hard time buying that Cas’s immediate solution to find out what happened to Yana was to start using Deleria? That feels like a bit of a jump.

I could relate to her intense love (obsession) with Yana, as many of us have had with a first love. That being said, their chemistry was hard to buy into given a lack of details about their background/relationship. Perhaps it just adds to Yana’s mystery?

Feeling a little mixed, but I would definitely try something else from this author again.

Thank you to NetGalley and the publisher for the ARC of Our Infinite and Inevitable Ends by A.D. Sui.

This is set in a near future where climate change has wrecked a lot of things, and there is a drug that lets people see different timelines. The main character, Cas, gets pulled into all of that while trying to figure out what really happened.

The premise is very much my thing. Fate, connection, alternate timelines. I should have loved this.

I did really like how the book handled climate change. It felt important and relevant without being preachy, which I appreciated.

But at the end of the day, if I do not care about the main character, I am not going to care about the book. And that was the issue here. I didn’t hate her, but I also didn’t find her interesting enough to be invested.

There were a few moments that worked, and I can see what the book was going for, but overall it just felt kind of middle of the road for me.

This is a solid 3 star read for me. Not bad, just not something I will continue to think about.

Thank you to ECW Press and NetGalley for providing a doorway into this shimmering sapphic sci-fi. Set at a time where climate crisis has reached it's peak, Big Pharma presents deleria, a drug that will let you explore alternate timelines and perhaps hold the key to saving the world. Deleria is also able to connect folks with loved ones who have passed, and quickly the street use is out of control.

A.D. Sui touches on such an interesting triangle of lesbian, climate crisis, and grief. Who wouldn't take a drug to spend more time with a loved one taken too soon, especially if it meant you could spend time with them in a reality they wouldn't die? Throw in being monitored by your ex-girlfriends last girlfriend overseeing your drug habits to see your mutual ex at a time when the rain is acid and the air is toxic - well - you've got a lot going on. I did get a little disoriented at times, which I think is intentional but overall loved a novel with all main characters being sapphic academics !

[Petri · Rating 4 out of 5]

I received an ARC for this book from NetGalley for free.

A dystopian sapphic sci-fi thriller about the earth being destroyed by climate change and mind altering drugs that lets us glimpse alternative timelines. I found this extremely well written and the worldbuilding and characters were top notch. I really enjoyed how at times this read like a sapphic soap opera but with a distinct sci-fi touch.

My only problem with this was that with the high stakes of earth closing on imminent destruction via climate change, I thought this would be grander and more action oriented. Instead this was quite an intimate human lead drama. I didn’t mind that either but was left wanting more.

Also one thing I really loved about this was that there wasn’t a single important male character in the book. ‘Cause let’s be real; who gives a fuck about men.

Will definitely be checking out the author's other work as well.

[Peter · Rating 4 out of 5]

Complex sci-fi tech fantasy, set in an, and many, alternative future Canadas. Where climate change has brought catastrophe, acid rain and other world wide problems.

A story mired in drug mis-use, government agencies and human relationships. The sort of story that, for quite some time, you don’t quite know what is going on. But because of that you keep reading because you want, no need, things to be made clear. Yana’s death leaves Cassandra, bereft and searching for reasons why? But Cassandra isn’t the only one looking, like the reader, for clarity and answers.

When you get to the end expect to see that clarity revealed through what turns out to be a love story.

In some ways the relationships are the biggest part of the whole and at the centre of this story. Holding on to love, and letting go. Being emotionally selfish in love or intentionally altruistic in the extreme.

[Hope · Rating 4 out of 5]

I've found a new genre to be obsessed with, cli-fi. The dystopian climate fucked world piqued my interest. It's very relatable at times and also a very scary (and hopeful?) view into our future.

Because about 95% of this book takes place in different realities, the actual storyline and characters fell a bit flat. It's escapism at its finest until there's nothing tangible left. Cas seemed to be obsessed with a version of someone that either never existed or hadn't existed in a long time, which also kind of accentuates the theme of escapism.

While a though read at times (due to the general detachment of the events happening) I feel like it does touch upon really important topics. We need to act, now, and not lose ourselves trying to find a perfect solution. It may be possible to fix things but only if we do something.

The world is in crisis, air quality is poor and there is acid in the rain. An island the size of Texas, made of plastic floats in the ocean. Scientists used to look to answers in their own reality but after the discovery of a drug that allows people to witness one of the millions of other realities the only research going in is looking for a quick fix from another world.

Cass is one of the few people looking for a fix in her own reality but then the woman who discovered the wonder drug blows herself and her research institute up Cass is pulled away from her research and has to figure out what happened. After all that woman was the love of her life.

A propulsive and interesting read, not too hard to follow considering the subject matter and a satisfying ending. The characters are flawed and messy which makes.complete sense in this flawed and messy world.

[Joanna · Rating 2 out of 5]

Unfortunately this didn’t do it for me. I can see how others may enjoy it; it could be I just wasn’t in the right mood for this bleak dystopian cli-fi read.

The first 5% of the book, based in the Garbage Patch, piqued my interest and I thought this was going to be a winner. Then I was slogging through the next 95% and looking forward to the end. The constant ruminating on the absent character Yana, the flat character of the MC, Cassandra, poorly explained science, and the odd writing style detracted enough from the book to make it unenjoyable for me.

I was immediately locked into Cass and Yana’s story right off the bat. Didn’t even need to know anything about them, but the two scientists pulled me IN.

And it kept getting more intense by the chapter!

This for me was so different than any other book I’ve read because I don’t delve too much into the sci-fi realm anymore and gosh am I happy to be back! I guess this would be considered more of the genre Climate Sci-Fi, but nevertheless, great.


Good story, fleshy plot development and so good. I had to go back and reread the last chapter when I picked it back up because it’s just detailed.

I do love the cover though!

This book's blurb comparisons made it sound so good and exciting and up my alley.

I just couldn't connect with these characters. Their motivations and cations didn't seem to line up or make sense to me at times.

This is about mysterious research and identity. And that had so much potential. Maybe I just wasn't in the mood for it? I don't know.

What I enjoyed

THe writing was fantastic & at times the book was quite thought provoking.

I can’t say at any point I was bored, there was so much going on though sometimes it was a little hard to keep up with.

While the premise was so interesting I just couldn’t get behind the characters, I found Cassandra a terrible main character & just didn’t care what happened to her.

All in all, I would recommend it to certain friends but it just wasn’t for me.

[Kat Reads Booksss · Rating 4 out of 5]

After The Iron Garden Sutra, I was really excited to read another book by A.D. Sui, and Our Infinite and Inevitable Ends was amazing! I loved the overall story, there are some really strong sci-fi ideas about climate change and alternate realities, plus the ending was brilliant.

I did struggle a bit in the middle, mainly because the characters were quite unlikeable and frustrating, but I think they had to be that way for the story to work.

As always, A.D. Sui writes in a beautiful, thought-provoking way.

Thank you to NetGalley and ECW Press for the ARC in exchange for my honest review.

Our Infinite and Inevitable Ends by A. D. Sui is a stunning introspection into the problems surrounding climate action and corporate greed, interspersed with a touch of sapphic angst. The novel follows Dr. Cassandra Barlowe, a scientist working towards finding plastic-eating mircoorganisms in the pacfic garbage patch. After she recieves a call from an old friend/lover/situationship moments before said friend blows herself up, Dr. Barlowe is forced by sadistic government agents to figure out what happened. If she can't, Cas will be imprisoned for domestic terrorism.
A. D. Sui creates a diverse and imperfect cast of characters that are just likeable enough for you to want the happy ending. Their flaws are beautiful to behold, creating a stunning emotional tone throughout the piece. Cas knows that her connection to Yana is unstable, and in following her wishes she may damn herself to addiction, and Okazaki is fully aware of the ethical quandries of her work; she will do anything for results.
Content wise, the novel is strikingly blunt in its criticisms of our current methods of dealing with climate change, but also weaves in more subtle themes surrounding academia and ethics. The plot did drag a tiny bit at times, and you really needed to work to understand everything all the time.
Overall, Our Infinite and Inevitable Ends recieves a 4.5/5 star review from me! I truly loved reading it. Thank you to ECW Press for providing this novel for review consideration via NetGalley. All opinions are my own.

I love mysteries through memory and time, and OUR INFINITE AND INEVITABLE ENDS is a new favourite. Sui layers memory, multiple realities, science, and yearing for better lives, in a surreal but always plausible plot, where every element is balanced and pitch perfect. Also, Sandra Ozaki has my heart. Highly reccomend.

Immediately hooked me. Really engaging story with an important message. The setting was very interesting and loved the recognizable places as a Canadian. Don’t want to say to much as it’s a beautiful ride and I recommend going in as blind as possible.
