It's no secret that I'm a big fan of Fonda Lee's books. And apparently I'm not the only one - her adult fantasy book, Jade City, was up for a Nebula this year and at the same time, her YA SF book Exo, has been nominated for the Andre Norton Award.

Cross Fire is the direct sequel to Exo, and picks up the story shortly after its predecessor left off. The alien Mur Zhree who colonized Earth over a century ago with mixed reception, but on balance arguably to the benefit of Earth, may now hav

A major step-up from the mostly successful first book sees a much more mature Donovan Reyes dealing with an increasingly precarious alien-occupied Earth.

The Rii are coming, and the Mur Erzen Commonwealth are getting ready to abandon Earth, taking with them only a small population of their most fit and trusted humans. The human resistance organization Sapience and its various splinter groups are growing stronger with the zhree pulling back and there's a lot of pressure on SetPac forces to keep or

Cross Fire is an excellent follow up to Exo. It's close, but I might have actually preferred it actually. I do know one thing for sure though: Fonda Lee is quickly becoming one of my favorite authors. Her characters, world-building, and action scenes are all very vivid and the pacing is just right. This series deserves all the love it can get.

I screamed about Exo last year, I'm gonna scream about Cross Fire today.
Because HOLY HECK THIS BOOK IS AMAZING and has set the bar for YA sci-fi super high for me.

- Cross Fire is the sequel to Exo and extends the post-apocalyptic story of humanity who are now subservient to an alien colonist species.
- This book takes the story to new heights. Humanity is warring with each other, divided by their allegiance to either the colonists or the human species -- and then something happens that changes e

I think this sequel to Fonda Lee's Exo is better than her first book, despite a somewhat slow start. The Zhree decide that Earth is too far away and costly to manage, and decide to abandon the planet, seeking to rescue 90,000 inhabitants to preserve the human species, with a focus on the hardened Exo's. Meanwhile, tensions among the core humans are led by rebel groups called Sapience and True Sapience. We continue to watch events develop through Donovan Reyes, the son of the former Prime Liaison ...more

Originally reviewed for YA Books Central:

Smart, well-paced, and intensely thought provoking. This series is on track to redefine sci-fi expectations for the YA genre.

Once again, the story is told in third-person past tense—entirely from the viewpoint of young soldier Donovan Reyes. Donovan is still mentally recovering from his time in captivity, and the loss of both parents to opposing ends of the conflict over the alien colonization of Earth. His instill

(A) 97% | AGES 14+ | Okay, I know that this doesn’t follow my review rules, because technically I rate 5* books 100%, but I don’t think I’ll ever find a SUPER PERFECT favorite book. But this book absolutely comes close and it still deserves a 5* rating. Plus, I am a little biased. :P
This book is so good it could be a movie. It’s so original! Also, this was my first YA book I’d had ever written, and so it holds a piece of my heart with it. I cannot get enough of this writing. It’s the best in the

That was an emotional rollercoaster from start to finish. Aside from the incredible action and pacing, I think this book contains excellent character development and is thematically rich and worth talking about.
I had a lot of mixed feelings about book 1 and its handling of the topic of colonization; some of those issues were addressed in this book, others not so much. Key turning point: Donovan's character finally realizes that most zhree don't value humans except when assimilated and harmless/l
So if I really enjoyed Exo despite having some issues with it, I liked Crossfire even better and didn't have anything like the same critiques of the world and character development that I did with the first installment. The addition of a larger political context to the relevant setting, the greater wealth of information we learn about the zhree, and a particular development about 2/3 of the way into the book that knits together puzzle piece hints dropped earlier in the plot (in a way where the t ...more

The first half is more character driven, while the second half is more action packed and plot-driven. I really liked the complexity throughout.

I loved Fonda Lee’s phenomenal YA dystopia novel Exo, in which aliens have conquered Earth and humans are a colonized species. This follow-up, Cross Fire, does not disappoint. That said, I suggest you go and read Exo before you keep reading my review of Cross Fire — this review will contain some spoilers for the first book.

The home planet is considering withdrawing from Earth, which may be too costly to defend. Only, if the Zhree withdraw Earth and all humans will inevitably die — humanity isn’t

Crossfire, by Fonda Lee, is the science fiction sequel to the popular book Exo. Donovan Reyes, the protagonist, is certainly no ordinary man. He is an exo, or a human possessing an exocell. Implanted using a special procedure, exocells allow for heightened strength and intelligence compared to “squishies”, or ordinary humans. Having an exocell has never been more important, for Donovan resides on a vulnerable Earth, where humans are ruled by a superior alien species, known as the Zhree. They pro ...more

"Cross Fire" was a great sequel to Exo that wraps up all the major plotlines and possibilities. The zhree, an alien race, are divided between Mur and Rii. The Mur have colonized Earth over a hundred years ago and work side-by-side with many humans in groups they call erze (kind of like a family group, organized by skill). Some of these humans are hardened (called Exos), which means they were given an exocel when they were young, which gives them protection, strength, and other finer skills. The ...more

Just as good as book 1.

I enjoyed how high the stakes were in this book, and I loved the fast-paced action and twist filled plot. The development of Donovan was wonderful to watch, and though I’m still a little iffy about his relationship with Anya, it seemed to work for this installment. One thing I wasn’t crazy about was Jet. He didn’t show up too much in book 1 (looking back, thank god), but he played a much bigger role in the sequel. Though his str

This book was super interesting, and had me on the edge of my seat while I was reading it. Cross Fire by Fonda Lee is a science fiction novel about an exo soldier named Donovan after the third world war when aliens ended up conquering earth and converting humans into hardened exos. In the middle of the book, Earth is attacked andd conquered by more aliens, which is bad news for every thing on the planet. One meaningful passage is found on page 247-248. It is spoken by Donovan after he goes and t ...more

The second is just as good as the first. Same extremely nuanced morality, same incredibly difficult situations, same complex moral choices without resorting to the grimdark or people just being generally awful. I cannot recommend this book series highly enough, especially for intelligent young children. Most books for young children are fairly morally straightforward. There is simply good guys and bad guys and while people make mistakes it's still pretty easy to tell. The next step up adds the s ...more

Cross Fire was a really good sequel to Exo. It kept me highly entertained, there was plenty of action, and the politics was amazing. I loved direction this series is heading and I enjoyed it immensely. Fonda Lee writes such unique stories that are all her own. I love her writing. Even though Donovan was not my favorite person in the first book, he came a long way in this book. Instead of trying to be one thing, and Exo, he was learning to make his own decisions and what it means to do the right ...more

One of the hardest things to do is to write a sequel set in an already strongly built world and bring in new readers without a ton of "previouslies" or assuming that the reader has already been in this world. This book does it, and does it well. To be honest, I didn't even realize this was a sequel!

The idea that aliens have invaded, that some humans have not only decided to work with them but also undergo a procedure to become more like them, doesn't feel new (one could imagine this as an allego

CROSS FIRE builds and expands on the ideas and themes from EXO, the first novel in the series. Like it's predecessor, it doesn't take long for the action to start, and Donovan finds himself once again at the center of conflict between Earth's alien occupiers, the anti-alien underground, and his own role as both exo and heir to his mother and father's legacies.

Fonda excels at writing fast-paced and thought-provoking scenes with characters who have much more depth than the usual YA melodramas. She

***4.5 stars***

While I liked the first book, I must say this was a stellar improvement upon it in my opinion. The story seemed to grow up in a way, concerning itself less with petty internal affairs and more with fate of all of humanity. Donovan was the same semi-impulsive character, but with far more wisdom this time around and I appreciated this balance so much. He clearly grew up as a character and the things he was puzzling through were far deeper than before and thus made his struggles far

An exciting conclusion to a story that expands the Zhree colonization established on Earth to something galactic. Donovan went through hell in book 1 and in this one he continues to make his own choices and involve himself in world events. He's a constantly evolving character who is a delight to follow.

This book includes more interactions between Donovan and a few Zhree that I really enjoyed (Therid, Worth, and Wilt) as well as giving us a glimpse into his training (wished for more of that!). A

Action packed sequel to Exo. The story picks up just about a six months or so after where Exo ended. Donovan is getting himself together after being kidnapped by the underground human terrorist group, Sapience, by integrating back in to normal life - drills and missions with his fellow soldiers-in-erze. I enjoyed this book as it took some unexpected turns as Donovan receives a message from father (who died in the last book) and makes some truly history changing decisions for his people and the f ...more

This was so good!

I hadn't been aware that Exo would get a sequel when I read an ARC of it years ago, but I'm so glad it did! Cross Fire was unexpected, and therefore I had no idea where the story would go. But it certainly went places! It expanded an already cool, unique world. It was a soldier's war story, framed with a little bit of romance, family, science and aliens. I mean there's no reason not to love it.

It was a very satisfying, if not bittersweet ending for these characters. Now I hope t

Ok, rarely do I feel a young adult sci fi book is worth 5 stars, but this one hits all the marks of great sci fi. The characters are deep and well developed. The relationships are a major part of the story. I love the focus on politics and the struggle that goes into making peace with everyone’s ideas and different view points. I love that there are still battles and there are hard losses and great victories in the battle. The romance is so realistic to me- I loved it. I also loved the open ende ...more

This is the book Cross Fire, by Fonda Lee. In the book, an alien race is running Earth. They decide to leave, and before they do, another alien race attacks. A group of humans, called Exos, have a sort of shield that they can move around their body to protect certain parts, or completely cover their body. They decide to try and fight against the invading aliens. My favorite part of the book is sort of a spoiler, even though it isn't at the end. However, it is still a very major point in the stor ...more

An unexpected sequel to an unexpectedly good series. I was intrigued, conflicted (by events and philosophies), frustrated (by hard headed characters), worried (we see many battles), and proud (the characters come so far from where they used to be). I was satisfied with where this series went and would not mind another book to further round out what will happen in the future of this alternate world Lee has created.
