Faron Vincent can channel the power of the gods. Five years ago, she used her divine magic to liberate her island from its enemies, the dragon-riding Langley Empire. But now, at seventeen, Faron is all powered up with no wars to fight. She's a legend to her people and a nuisance to her neighbours.

When she's forced to attend an international peace summit, Faron expects that she will perform tricks like a trained pet and then go home. She doesn't expect her older sister, Elara, forming an unprecedented bond with an enemy dragon-or the gods claiming the only way to break that bond is to kill her sister.

As Faron's desperation to find another solution takes her down a dark path, and Elara discovers the shocking secrets at the heart of the Langley Empire, both must make difficult choices that will shape each other's lives, as well as the fate of their world.
