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

Then a stranger’s blood changed everything.

Born into a world run by fear and dogma, Fyren lives a brutal existence. Her sole aim? Protect her sister. So when the gods mark her sister for death, Fyren takes her place.

But her sacrifice goes awry. Revived by arcane magic, Fyren wakes among her people’s longstanding enemies, changed, and with their violet blood in her veins. And her sister’s peril has only worsened. It’s up to Fyren to save her sister from the cult of their upbringing, 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.

Transformed, kidnapped, and thrust into a violent inter-kingdom conflict, 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 saving her sister is hardly Fyren’s biggest problem. Unwittingly, Fyren finds herself at the center of a game she never wanted to play—a game where one wrong move will tip her world into chaos.
