With over 10 million copies sold, The Expanse has become one of the biggest science fiction phenomenons of the decade.

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. Now a Prime Original series.

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.
