As an elite spy and the Queen's Third-in-Command, Aya has dedicated herself to a life of discipline and duty, using her gods-given abilities to keep dark magic from ever returning to the realm. Her oath ensures she will always act to protect those she fights alongside―including Will, the Queen's Enforcer and Aya's bitter rival.

Forced by circumstance to work together, Aya and Will struggle to come to an uneasy truce. But when tragedy strikes, Aya instinctively reacts, unleashing a power that hasn't been seen in over 500 years. Shaken, she's confronted with an impossible truth, one that threatens the precious grip she keeps on her control, that forces her to work with Will to discover who―or what―she really is, and that could turn her into a weapon in a war she doesn't know how to win.

With Will at her side and untold power at her fingertips, Aya will have to decide if she's been sent to save the realm she loves…or destroy it.
