Seventeen-year-old Daphne Janus goes to an island retreat with her neighbor and best friend, Cam. She doesn't know that she's been sent for experimental "suicide therapy" that crosses ethical lines--something the doctor calls "living art." Between the legends of the Chumash Indians, the ghost stories, and Cam's blatant lies, Daphne doesn't know what's real and what's a therapeutic exercise orchestrated by the Purgatorium, nor does she know whom to trust. When her horse bucks her off during a trail ride, and she becomes lost on the "haunted" side of the island, she begins to wonder if her parents sent her there to help her or to punish her.
Hermie and Hestie never asked to be demigods. Unlike others of their kind, they aren’t interested in going on quests and being the center of a world-changing prophecy. But when Zeus learns of Apollo’s vision–of the twins finding Prometheus, Zeus’s number one enemy–the hunt for Prometheus begins. Zeus and his allies want to bind Prometheus and kill the twins before their threat of a revolution becomes a possibility. If Hermie and Hestie don’t find the Titan first, they have no chance of fulfilling their destiny or of surviving Zeus’s threat against them.
