Haunted by what he has lost, Lucian has abandoned the life he knew seeking refuge from the world in Antares.

But when a mysterious woman brings word of a darkness stirring in Arundel, she offers him something far more dangerous than hope: a way to save his people.

Drawn back to the city he left behind, Lucian must confront the truth of his Caelesti heritage and the power that should have died with it. Yet the deeper he reaches into what he was born to be, the less certain the man beneath it becomes. Old loyalties begin to fracture, buried rage finds new purpose, and the darkness threatening Arundel is no longer the only thing his people have reason to fear.
