But Holly is no typical teenage runaway: A sensitive child once contacted by voices she knew only as "the radio people," Holly is a lightning rod for psychic phenomena. Now, as she wanders deeper into the English countryside, visions and coincidences reorder her reality until they assume the aura of a nightmare brought to life. For Holly has caught the attention of a cabal of dangerous mystics, and their enemies. But her lost weekend is merely the prelude to a shocking disappearance that leaves her family irrevocably scarred.
