"Following a fight with her mother about her boyfriend, fifteen-year-old Holly Sykes slams the door on her family and her old life. But Holly is no typical teenage runaway: A sensitive child once contacted by voices she knew as "the radio people," Holly has caught the attention of dangerous mystics - and their enemies. But her lost weekend is merely the prelude to a shocking disappearance that leaves her family scarred. This unsolved mystery will echo through every decade of Holly's life, affecting all the people she loves - even the ones who are not yet born. A Cambridge scholar, an Iraq war reporter, a middle-aged writer exiled from the bestseller list - all have a part to play in this surreal, invisible war on the margins of our world."--Cover.
