The pacing and plotting of this series leaves something to be desired (just needs a little tightening) but I don't mind a bit because the characters are worth it! I was so excited to see this was Caro's book, and she absolutely was worth the wait. Levi was compelling and lovely, just exactly who Caro needed. I'll be continuing the series for Itzel (and maybe Victory and Victor?) for sure.

It took me a bit longer to get through this one compared to the prior two books in the series, HOWEVER, I loved this one the most! The tension not only between Levi and Caro, but also the concept of what makes us human (or monsters), was extremely well done. GR81 is an iconic character, as well, and the banter was top notch! I giggled more than I expected to and this provided an excellent distraction from the chaos (see what I did there?) that is life. If you love a snarky FMC, a snarky side character, and a mountain of an MMC who would do anything for the woman he likes (loves?), then this is a great book for you!
I especially loved the inclusion of new characters from the universe and hope to see more of them (if there are more books in the series/offspring off this series). I know who I want the next book to be about!

I took the time and slowly went through the first two books to get a feel for the third and it helped to not feel a stranger in this world. I can also say that i loved them and the third was such a fun read, it was entertaining between the pages.

Caro Ogunyemi is an engineer that is supposed to be resting when her ship's crew takes a break after a big mission. Instead, she decides to pick up a solo mission from an ex-boss who totally didn't give her all the facts. She is supposed to be breaking into a remote prison planet to extract two missing guards from his team who haven't been responding to any comms and also some important tech. What is left out is that the guards might not be communicating because it isn't safe to and oh the tech it is inside a super soldier! What starts off as an easy job ends up being so much more.
A fun and fast paced read!

CHAOS (Bramble, 352 pp., paperback, $19.99) is even the name of Fay’s third sci-fi romance adventure, and if you haven’t heard about this series yet then you have three books of nonstop thrills and pew-pew space lasers waiting for you. Our heroine is Caro Ogunyemi, a renegade engineer with a past she’s determined to keep secret. When a chance to repay some of her moral debt sends her on a solo mission to a high-tech prison planet, she recklessly jumps at it. There she finds Leviathan, a murderous super soldier controlled by an implanted chip that inexplicably fails the instant Caro touches him.

From there it’s a race to the finish, as prison riots, malfunctioning tech and inconvenient but irresistible attraction add twists and turns to this roller coaster of a plot.

this series is just consistently fun! This one had a lot of action and I love the adorable quippy nature of the whole series. I know I can pick these books up and have a good time no matter whole the couple is.

ARC kindly provided through netgalley but all thoughts are my own.

Due to Kobo no supporting the new Netgalley file type, I wasn't able to read this book in time to give it feedback. I still plan on reading it.

I thought this was very good and I will have to add this to the shop shelves. Thank you for the chance for us to review.

If Constance Fay isn't going to do anything else, she is going to have a hectic heroine. This book names are so on point. Caro is so chaotic but she is well intentioned and trying to remedy mistakes of her past and save a life or three while she's at it. Her love interest is a mind controlled solider that only seems to be able to snap out of it when he's in her presence. This book has all the drama, intrigue, action and bananapantsery that I've come to expect from a Constance Fay space opera. I just hope we get to the mysterious Itzel next! 3.5 stars!

I absolutely loved this book! The romance here is intense, passionate, and so well done. It’s not just about survival; it’s about them finding healing and freedom together. The world-building is fantastic. But what I loved most was the emotional depth. It wasn’t just a high-action story; it was about these two characters learning to trust each other, facing their pasts, and struggling for a future together. The book had me on the edge of my seat, and I couldn’t stop thinking about it even after I finished reading. If you love sci-fi romance with emotional depth and high stakes, this one is a must-read.

Completely missed the part where this was book 3. The premise is amazing but I didn't have time to finish the first books to properly review.

This book is everything I’ve come to expect from Constance Fay: it’s silly, it doesn’t take itself seriously at all, and it is just incredibly fun to read.

For those who aren’t familiar, this is the 3rd book of Fay’s *Uncharted Hearts* series of sci-fi space adventure romantic comedies. The books star the crew of the scout ship Calamity (which is also the title of the first book) as they go on adventures among the stars and find love. The first book was about the ship’s captain, Temper; the second was about Micah the ship’s medic; this time, it’s the Calamity’s engineer Caro’s turn.

Caro is mostly flying solo in this book. She gets a call from Ven, the former captain of the Calamity and Temper’s shitty ex, asking for her help rescuing someone from jail. Against her better judgement, she lets herself get talked into it, and the fact that the person she’s trying to rescue is extremely hot has absolutely nothing to do with it. So she finds herself on a prison planet run by the Pierce Family, one of the capital-F Families that controls everything and antagonists from earlier books (and from Caro’s past, personally, which we learn more about as the book goes on). There she meets the prisoner she’s trying to rescue; a research subject known only by his codename Leviathan. He’s gorgeous, and super buff, and huge; he’s also a mindless killing machine, a prototype Pierce supersoldier. Until Caro touches him; physical contact with her brings him out from under Pierce mind control, and allows him to become his own, kind self again, though with no memories of who he is. He does remember how to kiss, though.

Like I said: this book is extremely silly. It’s the story of an escape from the universe’s most absurd jail - it’s a prison exclusively for high-ranking members of Families that get into trouble, so it’s more like a spa where no one is allowed to leave than anything else. The relationship between Caro and Leviathan is utterly lacking in surprises, but it’s still fun to read about. There *are* surprises in Caro’s personal journey and the way the adventure plays out.

Overall, I think it’s weaker than the first two books, because it’s largely missing the rest of the found family of the crew of the Calamity. They’re not 100% absent, but their appearances are brief. I’m always a sucker for a good found family in my fiction, and I felt their lack. Though I will acknowledge that it was entirely appropriate for Caro, as a character, to try to do everything on her own here, and when they do show up Temper (lovingly) chews her out for it.

At the end of the day, this is a book that seeks to entertain and delight, and it accomplishes this with gusto.

I'm a big fan of this series, even though I shy away from romance mostly. It was fun to read more about Caro here and I love the way Fay's fleshing out characters more and more!

It was a good sci-fi romances. I really liked Caro. She was amazing and brilliant. She's fierce and opinionated. She knows what she wants and gets to it. Leviathan was an amazing, mysterious and deadly MMC. Loved their relationship and banter. They were made for each other.

I had a hard time with the world building. But I saw too late that it was the third book in the same universe. It's advertised as standalone in the same series but I think it's better to read them in order to fully understand what's going on.

I'll try reading the first one to see.

I really enjoyed "Chaos," especially seeing Caro's story unfold. Her mission to help her crew and confront her past by infiltrating a prison and controlling a super soldier with a touch? Pure fun. The ensuing hijinks and escape, mixed with a budding romance, made for a quick, engaging read. I'm also loving how each book expands the Uncharted Hearts universe and crew dynamics. The sci-fi romance was well done, balancing the steamy scenes with a compelling plot.

Chaos is the third book in the Uncharted Heart series, and we finally get to follow Caro! After Caro gets a message pertaining to the safety of her old crew she jumps at the chance to help them out especially since it's in a lab to do with her past. Things immediately go awry and she ends up imprisoned and being chased down by a super soldier, who she can reprogramme by touching. Hijinks ensue and escape plans take action all while a love story is unfolding. I really enjoyed this book and these characters and I look forward to reading more in this series!

Another fun installment in the Uncharted Hearts series. Each can be read as a stand-alone as they focus on a different character but there is a common thread running through. This is a sci-fi romance (or science friction as the author put it) which is a lot of fun. A lot of great banter in this one which I love.

Another fun installment of the Uncharted Hearts series where we get to know Caro, the engineer of the Calamity's crew. Caro intentionally get herself put in prison to help Victor and Victory and ends up with other priorities to help correct mistakes from her past that she encounters while in Shikigami.
These books are quick reads and I like how we learn more about the crew and the universe in which these books take place. I can't wait to see who the next book will feature.

The crew of the explorer ship Calamity is back. This time their engineer Caro Ogunyemi decides to help recover a stolen chip from inside a prison where the Pierce family is experimenting on prisoners to create a super soldier. She expects to use her hacker skills, but unfortunately her merest touch causes electronics to die because of a strange bug bite on their last exploration. The result is Chaos(paper from Bramble). She can get in the prison because she is wanted by the Pierce family and their only successful super soldier is being used to kill prisoners in gladiator maze fights. By holding his head in the right place, she can turn off the implant that keeps him under control. Constance Fay tells a great series and I’m looking forward to more adventures by other members of the crew.

Chaos by Constance Fay is fabulous.

Caro is an engineer on a starship with her best friends and has been on some interesting adventures lately. That comes to a head for Caro when she meets a super soldier in need of saving. And she is there to save him.

I love sci-fi romance and Constance Fay does it so well. The romance gets spicey but never overshadows the story of a man who needs help regaining his agency from a vile tech oligarch in (what feels like a not too distant) a space-faring future.

I hope we get more books in this universe!

If you like Jessie Mihalik, Kit Roacha, or Everina Maxwell, you will love The Uncharted Hearts series by Constance Fay.
