Who would have thought your dreams could kill you? Melaina makes the best of her peculiar heritage: half human and half Oneiroi, or dream spirit, she can manipulate others' dreams. At least working out the back of a new age store as a 'dream therapist' pays the bills. Barely. But when Melaina treats a client for possession by a nightmare creature, she unleashes the murderous wrath of the creature's master. He could be anywhere, inside anyone: a complete stranger or her dearest friend. Melaina must figure out who this hidden adversary is and what he's planning - before the nightmares come for her.
