Locus Award nominee 2013.
The action-packed sequel to James S.A. Corey’s science fiction debut, Leviathan Wakes.
We are not alone.
The alien protomolecule is clear evidence of an intelligence beyond human reckoning. No one knows what exactly is being built on Venus, but whatever it is, it is vast, powerful, and terrifying.
When a creature of unknown origin and seemingly impossible physiology attacks soldiers on Ganymede, the fragile balance of power in the Solar System shatters. Now, the race is on to discover if the protomolecule has escaped Venus, or if someone is building an army of super-soldiers.
Jim Holden is the center of it all. In spite of everything, he’s still the best man for the job to find out what happened on Ganymede. Either way, the protomolecule is loose and Holden must find a way to stop it before war engulfs the entire system.
CALIBAN’S WAR is an action-packed space adventure following in the footsteps of the critically acclaimed Leviathan Wakes.
The series
Humanity has reached the stars—but it’s still haunted by its oldest problems.
Read full series description
The Expanse begins not with a heroic mission or utopian dream, but with a missing girl and a mystery that pulls at the fragile threads of a solar system on the brink. Mars, Earth, and the scattered colonies of the Belt live in uneasy balance, each burdened by political tension, economic disparity, and centuries of mistrust. And then something ancient awakens.
What sets this science fiction epic apart isn’t just the scale—though it spans planets, factions, and eras—it’s the people caught in the chaos. A haunted ship’s captain with a stubborn moral compass. A foul-mouthed politician willing to burn worlds to save her own. A Belter detective chasing ghosts through dust and vacuum. Their stories intertwine not because fate demands it, but because the system they inhabit is collapsing—and they’re just awake enough to notice.
The world-building is dense and lived-in, with asteroid stations that feel rusted and claustrophobic, Martian warships that hum with quiet threat, and alien technologies that refuse to be understood. Yet amid the cosmic scope, the emotional core always stays human. The writing captures the intimacy of fear, loyalty, and hard choices, even when the stakes are planetary.
Adapted into a critically acclaimed television series, The Expanse has become a touchstone for modern space opera—not by echoing the past, but by carving its own orbit through the genre. It’s science fiction where the future looks eerily familiar, and the real alien threat might not be from beyond the stars, but from what we carry with us into them.
