Around the world, black handprints are appearing on doorways, scorched there by winged strangers who have crept through a slit in the sky. In a dark and dusty shop, a devil's supply of human teeth grown dangerously low. And in the tangled lanes of Prague, a young art student is about to be caught up in a brutal otherwordly war.

The dream chooses the dreamer, not the other way around - and Lazlo Strange, war orphan and junior librarian, has always feared that his dream chose poorly. Since he was five years old, he's been obsessed with the mythic lost city of Weep, but it would take someone bolder than he to cross half the world in search of it. Then a stunning opportunity presents itself in the person of a hero called the Godslayer and a band of legendary warriors, and he has to seize his chance or lose his dream forever.

In the wake of tragedy, neither Lazlo nor Sarai are who they were before. One a god, the other a ghost, they struggle to grasp the new boundaries of their selves as dark-minded Minya holds them hostage, intent on vengeance against Weep. Lazlo faces an unthinkable choice—save the woman he loves, or everyone else?—while Sarai feels more helpless than ever. But is she? Sometimes, only the direst need can teach us our own depths, and Sarai, the muse of nightmares, has not yet discovered what she's capable of.
