I won't spoil this for those who have not started the series, but I will say that this sequel is superior to the first book in every way. It introduces a host of fascinating new characters, both human and alien, and sends familiar characters into surprising (even shocking) uncharted places. Carryx civilization is further illuminated for the reader and the more we learn, the more I want this to be more than just a trilogy. I rated the first book - The Mercy of Gods - a little lower than this one but it is definitely worth reading to set up this excellent book and what I anticipate will be a remarkable finale. Anyone who read The Expanse is aware that James S.A. Corey knows how to stick the landing.
From the multi-million-copy bestselling author of the Expanse comes the second book in the Captive's War series - a spectacular new space opera that sees humanity fighting for its survival in a war as old as the universe itself.
The monstrous Carryx empire was built by subjugation and war. Thousands of species are bound to their Sovran's command in an endless, blood-soaked test: be useful in the eternal conflict or be slaughtered.
Dafyd Alkhor, highest among their human captives, is feared and despised by the very people he champions. Ruthless in carving out his niche in the eternal war machine of the empire, he will reshape human nature itself as a tool for their alien masters' use. But Dafyd's loyalty is not what it seems.
The Swarm, an agent of the Carryx's deathless enemy, has been smuggled into the Carryx world-palace along with the human slaves. Its mission: discover a way to bring down the empire's eternal reign. But the longer it lives among and within humanity, the more it forgets that it is a weapon.
As the human captives spread through the battlefronts of empire, the awesome power of the Carryx becomes clear. And with it, a desperate plan for their destruction.But empires hide secrets, and even the deathless enemy may not be what it appears . . .

Full series details →The series
On a distant world, generations of humans have lived without any memory of how they got there. Their society—isolated, quietly advanced, and curiously untouched—unfolds beneath the looming question of origin. And then the Carryx arrive.
Read full series description
Everything changes the moment this insectoid empire descends. Alien in every sense, the Carryx don’t seek war in the way humanity understands it. They don’t conquer with brutality—they absorb, repurpose, and twist. Their captives become tools, their cultures become resources. When a group of scientists and scholars from Anjiin are taken, they’re not imprisoned behind bars—they're immersed in the machinery of an empire that doesn’t believe it’s doing anything wrong.
The Captive’s War peels back the traditional layers of alien invasion and reframes them through quiet horror and psychological unease. It’s not about planetary battles or fleets in the sky—it’s about cultural survival, about what happens when resistance looks less like rebellion and more like remembering who you are in a world determined to erase that knowledge.
The atmosphere is dense with tension—intimate, unsettling, and occasionally darkly beautiful. Fans of intelligent science fiction will find themselves caught between awe and dread as the Carryx civilization is revealed: not evil, but incompatible. It’s a conflict rooted in the fundamental disconnect of what it means to be alive, sentient, and free.
Written with the precision and human depth that defined The Expanse, this series opens a new frontier—one where the most devastating wars are fought not with weapons, but with assimilation, ideology, and memory.
