When sleep became fatal, half the world died unaware in their beds. And anyone who falls asleep now will never wake again. Those who've survived -- the insomniacs, vagrants, and night shift workers -- have been thrown into an apocalypse where stimulants are king and every minute matters. After a meth binge inadvertently saves him from "the big sleep," addict Jake becomes an unlikely anti-hero in a cross-country quest to save the world. Together with a crew of misfit survivors -- including an overnight nurse, a red-eye pilot, and a mysterious insomniac -- Jake battles desperate militants, sleepless psychotics, and his own looming fatigue as he searches for answers... and just maybe a way to sleep again. Welcome to Day 5.
