A Houston college student, McKenzie Lewis, can track fae by reading the shadows they leave behind. For years she has been working for the fae king, tracking rebels who would claim the Realm. Her job isn't her only secret. She's in love with Kyol, the King's sword master-but human and fae relationships are forbidden. When McKenzie is captured by Aren, the fierce rebel leader, she learns that not everything is as she thought. And McKenzie must decide who to trust and where she stands in the face of a cataclysmic civil war.
