Dr. Evelyn Hashimoto (or "just Evie") is a young woman who has a predilection for books about domesticated chickens and a penchant for dyeing her hair purple (among various other colors). She has known since she was a child that she has the ability to change the course of one's fate--but she has kept these abilities hidden and suppressed through a maze of secrets.
But when a series of mysterious occurrences bring her secrets to the surface, she soon discovers that she cannot keep them to herself any longer. A new world opens up to her through the guidance from a shadow--the son of death himself. His father is the wearer of the Obsidian Crown, the reigning monarch of a world that has been hidden from humans for thousands of years. Though Evie begins to trust her shadow friend, she starts to realize that he is not the only shadow surrounding her--shadows with faces and claws that drip with blood and death. Ultimately, she places her faith in the son of death himself, standing on the precipice of a war that has long since been thought of as over.
