Once they were strangers bound by their fears of a demonic entity called Elizabeth Wither. They saw her come to life on Halloween in the historic college town of Windale, Massachusetts. They saw their dark dreams come true by the terror she wrought. They watched her crushing death in tons of falling stone. But if Wither is gone and their nightmares are over, why do they wake up screaming?

Wendy Ward -- a college student with a gift for white magic -- can sense that the town of Windale is in for a dramatic change in weather. There's a new chill in the air....It's whispered in the warnings of an old woman. It's hidden in the corrupting legacy of a newborn baby. It's waiting in an ancient evil impatient for a human host. And it's being carried in the creeping flow of black blood -- Wither's rain.
