A black moon had risen, a sphere of sleeplessness that pulled at the tides of blood - and invisible explanation for the madness welling inside. The world has stopped sleeping. Restless nights have grown into days of panic, delirium and, eventually, desperation. But few and far between, sleepers can still be found - a gift they quickly learn to hide. For those still with the ability to dream are about to enter a waking nightmare. Matt Biggs is one of the few sleepers. His wife Carolyn however, no stranger to insomnia, is on the very brink of exhaustion. After six restless days and nights, Biggs wakes to find her gone. He stumbles out of the house in search of her to find a world awash with pandemonium, a rapidly collapsing reality. Sleep, it seems, is now the rarest and most precious commodity.
