She was commanded to kill him with a single strike to the heart. She didn't expect her own to betray her.

Sylina has sacrificed everything for her goddess-her soul, her freedom, her eyes. Life in service to the Arachessen, a cult of the Goddess of Fate, has turned Sylina from orphaned street-rat to disciplined killer, determined to overthrow Glaea's tyrannical king.

But when a brutal vampire conqueror arrives on their shores, Sylina faces an even deadlier adversary. She's tasked with a crucial mission: infiltrate his army, earn his trust. . . and kill him.

Atrius is a terrifying warrior carving an unstoppable path through Glaea. Yet when Sylina becomes his seer, she glimpses a dark and shocking past-and a side of him that reminds her far too much of parts of herself she'd rather forget.
