It's been twenty three days since Quinn has slept for more than minutes at a time. Demons have invaded her dreams, stalking her, and whispering of her death. The lack of sleep and crippling fear are ruining her life. Energy drinks and caffeine pills don't make a dent. When Quinn dozes off in the school hallway, Aaron, an amnesiac with a psychic ability, accidentally enters her nightmare. The demons are determined to keep them apart, and Aaron from discovering the secret locked away in his memory. Together, they could banish the darkness back to the underworld for good. That is, unless the demons kill them first.
