Sometimes, Nightmares walk the Earth.

Dream of the Endless is the unquestioned lord of all that happens when we sleep--including his most solemn duty, the creation of nightmares. It was his hand that formed the Corinthian, patron saint of serial murder, whose ravenous mouths have tasted the blood of sleepers for centuries. Once, years ago, the Corinthian escaped the Dreaming and entered the waking world--and the body count was vast. Dream eventually put that injustice to rights and un-created the Corinthian, remaking him as a more pliable nightmare, and bringing him back to his appointed task.

But now a new nightmare has escaped into the "real" world. Art student Madison Flynn sees this "Smiling Man" in her waking hours...and she's not alone. What's more, this monster is somehow, improbably, impossibly, a nightmare that Dream of the Endless did not create. And when he realizes this fact, the Corinthian will slip once more onto our plane and start a hunt for this mockery... but heaven help us all when his memories of his past hunts begin to return!
