Caliban's War

On Jupiter's moon Ganymede, a critical agricultural hub, a Martian marine unit is decimated by a monstrous, inexplicable supersoldier, leaving only one survivor. Simultaneously, a botanist desperately searches for his kidnapped daughter amidst the chaos, discovering she is caught in a sinister experiment. As tensions between Earth and Mars escalate to the brink of all-out war, a shrewd Earth politician uncovers a conspiracy to weaponize a terrifying alien protomolecule.

James Holden and the crew of the Rocinante are drawn into this escalating crisis, navigating a solar system on the verge of collapse. They must confront not only the political machinations threatening to ignite an interplanetary conflict but also the chilling evolution of the protomolecule itself. The fate of humanity hinges on uncovering the truth behind these events before a new, devastating alien weapon is unleashed.
