Twenty-one-year-old Leora Everen never believed in magic beyond the walls of the divide—until the day her brother is mauled by a creature from within it and begins to fade beneath a strange, darkening sickness. With no cure in Briarholt and her father forbidding her to help, Leora sets off and crosses into the forbidden land, desperate to save him. There, she meets Ronan Thalor, a sharp-tongued prince with a storm in his blood and secrets in his eyes. He claims to be tied to a forgotten prophecy that speaks of the need to save the walls of the divide. When a phoenix intervenes during an attack, something ancient awakens in Leora, revealing and binding her fate to Ronan in ways neither of them understand. As they journey through lands once ruled by elemental magic, Leora’s feelings for Ronan deepen—but so do the lies between them. Because Ronan knows the truth: to save the world, they may have to die. And love might not be enough to change fate. Magic is stirring. The walls are cracking. And the girl who just wanted to help her brother may be the only one who can stop the darkness—or set it free.
