Phoebe finds herself drawn to Mallory, the strange and secretive new kid in school, and the two girls become as close as sisters . . . until Mallory's magnetic older brother, Ryland, shows up during their junior year. Ryland has an immediate, exciting hold on Phoebe-but a dangerous hold, for she begins to question her feelings about her best friend and, worse, about herself. Soon she'll discover the shocking truth about Ryland and Mallory: that these two are visitors from the faerie realm who have come to collect on an age-old debt. Generations ago, the faerie queen promised Pheobe's ancestor five extraordinary sons in exchange for the sacrifice of one ordinary female heir. But in hundreds of years there hasn't been a single ordinary girl in the family, and now the faeries are dying. Could Phoebe be the first ordinary one? Could she save the faeries, or is she special enough to save herself?
