In the Five Worlds, magic is wealth—and Anouette alone possesses an endless supply she cannot wield. Bound by law to the Crown Prince of her home world, she risks everything at Caerdroia, a training institution for mages, to reclaim her power through forbidden study. Her defiance pits her against Soren, who is heir to a blood-soaked legacy and sworn to end her life. Tasked with killing her by the most powerful man in all the worlds, Soren is ensnared by their volatile attraction. Sparks fly into a dangerous attraction, forcing them to choose between duty, freedom, and a choice that could shatter the Five Worlds.
