Six months after Nemain defeated the warlock leadership known as the Circle, she's soaking in the freedom that comes with no longer being hunted. Her former lover turned enemy, Sebastian, is dead and the Circle has retreated in defeat. However, her reprieve comes to an end when a friend asks for a favor that she can't refuse. Not when it could lead to answers that Nemain wants and alliances she desperately needs.

After a young fae boy with extraordinary magic wandered into a remote village in one of the fae realms, the village was destroyed. No one knows the identities or allegiances of the fae who destroyed the village, but one thing was clear, their magic consumed other magic. They were devourers—or at least part devourer. While most didn't believe that was possible, Nemain certainly did. She had been hiding her devourer heritage for her entire life.

While Nemain and her friends set out to find the mysterious child and search for answers about the fae with magic so similar to hers, they discover that there are more secrets in their world than they ever thought possible. Old secrets, new secrets. Ancient secrets long forgotten. Secrets from both friend and foe. And Nemain is in the center of it all. Can she save herself and the fae child? And how much is she willing to sacrifice?
