Centuries ago, mortals split the realm into two, with a magical veil placed firmly between them and their immortal rulers, the Tiarcons. Fueled by stolen magic, the mortal kingdoms flourished, but the Tiarcons never stopped trying to reclaim their magic and mortal subjects. And now, generations later, the veil between realms has begun to tear, letting immortal monsters ravage across the nations and threaten all the mortals have built.

Alia Meador would happily watch the mortal kingdoms buckle, as long as she could keep herself and her teenaged daughter, Lena, alive. After all, her own kingdom of Mandal, cast her out for her volatile magic, sending her to wander remote villages for decades. But when the treatment for Lena's illness comes along with a royal order to defend Mandal with the same magic they once spurned, Alia is caught between protecting the one person she loves and the reckoning she's so long desired.

With every moment spent in Mandal, Alia is subjected to the grasping of her ruthless family, a traitorous mage determined to understand the extent of her power, and the allure of the prince she once loved. And with every immortal confrontation, Alia's magic comes closer and closer to consuming her.

As the balance between realms shifts, Alia has to decide if her realm is worth saving, or if it all needs to be undone.
