Weaveworld begins with a rug--a wondrous, magnificent rug--into which a world has been woven. It is the world of the Seerkind, a people more ancient than man, who possesses raptures--the power to make magic. In the last century they were hunted down by an unspeakable horror known as the Scourge, and, threatened with annihilation, they worked their strongest raptures to weave themselves and their culture into a rug for safekeeping. Since then, the rug has been guarded by human caretakers.

The last of the caretakers has just died.

Vying for possession of the rug is a spectrum of unforgettable characters: Suzanna, granddaughter of the last caretaker, who feels the pull of the Weaveworld long before she knows the extent of her own powers; Calhoun Mooney, a pigeon-raising clerk who finds the world he's always dreamed of in a fleeting glimpse of the rug; Immacolata, an exiled Seerkind witch intent on destroying her race even if it means calling back the Scourge; and her sidekick, Shadwell, the Salesman, who will sell the Weaveworld to the highest bidder.
