Caliban's war

720 pages

A high-stakes, cinematic space opera where gritty political maneuvering collides with terrifying alien unknowns.

What it feels like

Reading this feels like being strapped into a high-G burn, balancing the sheer scale of interplanetary conflict with the intimate, claustrophobic reality of life on a gunship. The narrative shifts seamlessly between sharp, cynical political maneuvering in Earth's halls of power and the visceral, boots-on-the-ground trauma of a Martian marine facing the impossible. It is a deeply cinematic experience, driven by a propulsive momentum that never sacrifices character depth for action. The atmosphere is thick with paranoia and the creeping dread of an alien unknown, yet anchored by the fierce, stubborn loyalty of a found family trying to do the right thing in a universe determined to tear itself apart. It will thrill readers who love their space operas gritty, grounded, and relentlessly paced.

About the book

The second book in the NYT best-selling 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. Now a Prime Original series.

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...
