After a fight with her mother, Holly slams the door on her family and her old life. 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. A Cambridge scholarship boy grooming himself for wealth and influence, a conflicted father who feels alive only while reporting on the war in Iraq, a middle-aged writer mourning his exile from the bestseller list-- all have a part to play in Holly's invisible war on the margins of our world.
