"Corey is always one of the most engaging voices in the genre." —Adrian Tchaikovsky, bestselling author of Children of Time

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 …
