Fifteen-year-old Aiko has never seen anyone like her before – until Fletcher arrives at her orphanage to free her, and tells her that they’re the last two Humans in the galaxy.
Aiko can’t accept that. How does he know they’re the last two? What happened to the rest of the Humans? Finding the answers will require Aiko to follow a trail Fletcher abandoned many years ago, when he was just her age.
But asking about Humans, it turns out, is the most dangerous thing she can do with her newfound freedom. It will take her to places she never dreamed of, and bring her face to face with a terrible truth…

I started out enjoying this book a lot, but I had to DNF when it became hard to follow.
I felt like it described every detail of what was going on ,purposely avoiding telling you what was going on, and after a while, it just got frustrating to me to try to puzzle things together in that way.
I quit at 65%, hoping things would come together it had so much potential.i wanted to finish. I genuinely hope that others have a better time than I did with it because so much about this was good. The characters, the pacing...
Just a few clarifying sentences here and there would have worked wonders, for me at least.

Fun read
Aiko's Dive checks all the boxes for a fun and engaging sci-fi novel. What I want from a Sci-Fi is unique science a different way of understanding the universe and compelling characters in the story has it all.

Think Star Wars meets Alien. I found this one difficult to begin with due to the different species names and the way it just went straight in without any explanations but it was also hard hitting emotion from the first chapter. I soon found myself engrossed in the story even if it was a little dark and thought provoking in parts. An enjoyable read especially for any sci-fi fans.

Aiko’s Dive is an enrapturing tale that had me hooked from the start. I’m a big fan when things shift to be a little more cosmically horror-centric, especially when it catches me by surprise. Aiko’s Dive did not disappoint!

The action never stops with this one! An exciting adventure that kept me glued to the pages til the very end. Teen audiences will love this especially.

amazing story
I devoured this book in three days. I’m at a loss for words but what I can say is that I adored this story and I cannot wait for book two to come out. I will be impatiently waiting.

This book was amazing! I loved the writing style, the characters, the pacing, everything. I don’t read sci-fi much, but I think this book makes me want to start

With imaginative universe-building and non-stop action, Aiko's Dive is a sci-fi adventure fans of Star Wars will enjoy.

I went into Aiko’s Dive expecting a fun, fast-paced YA sci-fi adventure, which I got, but what surprised me most was how emotionally grounded this story is. Beneath the alien tech, the starships, and the galaxy-spanning mystery is a deeply personal coming-of-age story about a girl trying to figure out who she is in a universe where her very existence might be a myth.
Fifteen-year-old Aiko has grown up in a damp, bleak orphanage surrounded by non-human caretakers and other orphans who look nothing like her. Her only friend, Fallah, doesn’t even speak the same language. The sense of isolation and otherness is palpable from the very beginning and when Fletcher arrives claiming they’re the last two humans in the galaxy, the existential weight of that statement hits hard.
Aiko questions. She pushes. She fights for answers in a world that would rather she stay quiet and I loved that about her. Her determination to uncover the truth about what happened to humanity drives the story, and it’s what kept me turning pages.
The writing is tight and purposeful. Every scene moves things forward, and even the quieter moments feel charged with emotional weight. Nothing here feels like filler, and that’s rare in sci-fi. There’s an elegance to how the plot unfolds.. it’s lean without sacrificing depth, and somehow still leaves room for big ideas.
As someone who grew up on human-centric space operas, I found the reversal here, humans as the rare, almost mythical species, really compelling. It makes you reflect on how we see ourselves in the universe, and what it means to be “alien.” That thematic inversion gives Aiko’s Dive a quietly subversive edge that I really appreciated.
What I loved:
Aiko’s tenacity, intelligence, and emotional depth
The sense of wonder and danger that comes with true freedom
The slow-unfolding mystery of what happened to humanity
The friendship with Fallah..it’s quiet, but meaningful
The balance between emotional storytelling and sharp sci-fi worldbuilding
If you're looking for a thoughtful, character-driven sci-fi that’s safe for younger readers but layered enough for adults to enjoy, Aiko’s Dive is absolutely worth picking up.
Can’t wait to see where this series goes next.

Aiko’s Dive
This dystopian sci-fi had a compelling premise and was fast paced and engaging. The story follows an orphaned human living in a universe dominated by other species. When she’s taken in by an adopter who isn’t quite a father figure so much as someone searching for his own kind, the two are pulled into a larger quest that quickly becomes more dangerous than expected.
The worldbuilding is intriguing and unfolds naturally. The plot moves quickly, and I found myself invested in both the tension and the growing mystery.
If you enjoy dystopian sci-fi’s this is well worth reading.

More than just another YA sci-fi read
This book is another stellar example of why YA isn't just for young readers. If you were never told the age of the protagonist, this book. Is as good as any other adult sci-fi novel. With gripping action, strong characters, and a compelling story, Falwell takes the reader on a wild journey through space on a quest to discover what happened to humanity.

I’m a huge sci-fi fan, and this book absolutely delivered. It follows a young girl as she uncovers the truth about her genetics while unknowingly hosting an unwelcome entity. As her journey unfolds, she begins to realize the entity may not be entirely harmful after all. The story gave me strong Venom and Aliens vibes—both of which I love—making this a storyline I thoroughly enjoyed.

Aliens, Kaisin, Humans, oh my.
I went into AIKO'S DIVE completely blind and finished this in three days! The writing is immersive, the world-building fantastic, and all the alien characters are so fun! This is the kind of story that's hard to fit into a box, but it still hits home. A wonderful blend of sci-fi, light cosmic horror, action, and mystery.
