Seventeen-year-old farm girl Branwen isn't afraid of the ancient burial mound hidden within the Welsh forest of Bryn Celli Ddu. The tales of its mystery and magic thrill her-until that same strange power drags her, kicking and screaming, through the dark tomb and into the realm of the fae. Escape seems nearly impossible when she is captured by servants of the vicious harpy-queen Celaeno. Branwen must use all of her wits and determination to survive in a cruel and beautiful land called the Sídhe, where everything-even kindness-has its price. When her indomitable spirit finally earns her a chance at freedom, Branwen must decide what or she is willing to sacrifice in order to return home.
