We are not alone.
On Ganymede, breadbasket of the outer planets, a Martian marine watches as her platoon is slaughtered by a monstrous supersoldier. On Earth, a high-level politician struggles to prevent interplanetary war from reigniting. And on Venus, an alien protomolecule has overrun the planet, wreaking massive, mysterious changes and threatening to spread out into the solar system.
In the vast wilderness of space, James Holden and the crew of the Rocinante have been keeping the peace for the Outer Planets Alliance. When they agree to help a scientist search war-torn Ganymede for a missing child, the future of humanity rests on whether a single ship can prevent an alien invasion that may have already begun . . .
Caliban's War is a breakneck science fiction adventure following the critically acclaimed Leviathan Wakes.
I really enjoyed this book, even more so than Leviathan Wakes, and that was great. This time around, I think the book is better than the TV show (too much chopped out so far), though there's still the second half of this book that season three of the TV show needs to cover.
For POV, Holden's still here, but gone is Miller's noir. In its place is Martian Marine Sgt Bobbie Draper, the political machinations of UN Assistant Undersecretary Chrisjen Avasarala, and the forlorn quest of Prax, a Ganymede biologist. It's a diverse cast with wildly different perspectives and personalities.
Prax's daughter was kidnapped just before the war started on Ganymede, so he spends all of his waking hours searching for her. He's wasting away, praying that she's still alive, but expecting the worst. By the time Holden and the others encounter him, he's so far gone that he's barely capable of speech.
Chrisjen is a foulmouthed bureaucrat. She cusses like a sailor, possibly worse. When asked why her language is so "colorful", she replies that it's to prevent others from thinking she's soft. Why would anyone think that of her? It's not because she's happily married and a grandmother. It's because she "won't kill children." It's a brutal insight into the political landscape of The Expanse. It's all a game, but she can't give it up because she doesn't trust the other players. Her repartee with Holden was excellent. I hope it holds up on the TV show. If it doesn't, it won't be because Shohreh Aghdashloo didn't hold up her end. Her portrayal of Chrisjen is spot on.
Bobbie's coping with PTSD after her squad was obliterated by the aforementioned "monstrous supersoldier" (I don't want to spoil it, but the title is a clue.). She wants answers; she wants revenge. IIRC, she's two meters tall and intimidates anyone who has a clue. And that's before she puts on battle armor. After the Martian government lets her down, she goes to work for Chrisjen, because she's the one person whose objectives are in line with her own. It's not without bumps along the way though. Bobbie is a stranger in a strange land and must confront her perceptions about Terrans (Mars seems a bit like Sparta).
So you have Bobbie and Chrisjen hunting down the bastards that made the supersoldiers while Prax and Holden's gang are searching for Prax's daughter. The plot lines converge, and all hell breaks loose. It's all so epic that I couldn't help but love it. I had too much fun reading this, which isn't an easy things for me to say about a book that's spitting distance from 600 pages. I can't wait to see season three and read Abaddon's Gate.
