Book Summary

The second book in the New York Times bestselling Expanse series, Caliban's War shows a solar system on the brink of war, and the only hope of peace rests on James Holden and the crew of the Rocinante's shoulders. 

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 ...

Media Reviews

"This breakneck tale will have readers itching for book three." ―Publishers Weekly

"A worthy sequel to Leviathan's Wake. Compelling characters and a plot that combines political intrigue with military sf create a memorable story that begs for film adaptation." ―Library Journal

"Caliban's War is even better than Leviathan Wakes. It's old-fashioned space opera, the kind of SF that I cut my teeth on, a real page-turner set in a vividly imagined solar system... superlatively written." ―George R.R. Martin, New York Times bestselling author of A Game of Thrones
