It was a simple trade: Fyren’s life for her twin’s.

Then a stranger’s blood changed everything.

Born in the shadow of ruthless dogma, Fyren has one aim: protect her twin sister. So when the gods mark her twin for death, Fyren takes her place.

But her sacrifice goes awry. Instead of dying, Fyren wakes among her enemies, revived by their magic, with their violet blood in her veins. And, her twin remains trapped in the cult of their upbringing. Only Fyren can save her, but there’s one complication: Fyren’s rescuers aren’t about to let her go.

Not when she might be the key to saving their kingdom.

Fyren plots her escape in earnest. But as a forbidden power emerges, foreign threats loom, and the line between friend and enemy thins, it becomes clear that fleeing her saviors turned captors is hardly Fyren’s biggest problem. Unwittingly, she finds herself at the center of a centuries-old conflict——one in which a single wrong move will tip her world into chaos.
