After experiencing terrifying visions, Daire Santos goes to live with her Grandmother in the town of Enchantment, controlled by the evil Richter family, who are determined to rule over the Lowerworld, Middle World and Upper World. There, she discovers that she's a Soul Seeker - a person who can navigate between the living and the dead - and learns to harness her powers, which she can use to stop the Richters. But she is in love with Dace Richter, whose twin brother Cade is a shape-shifter, out to steal Daire's powers.
