He's here. Amanda Young doesn’t know who…or how…or why. She only knows that evil has come to Port Isley, the picturesque seaside village she calls home. It arrives on the wings of summer, in the guise of a sinister, nameless man crowded among the tourists from Seattle. He’s there when Amanda has a premonition of a classmate’s murder and when the girl’s mutilated body is discovered hours later. He’s lurking nearby when the neighbors she’s known forever inexplicably begin to…change. There — when their suddenly raging emotions transform them into lustful, violent shadows of themselves. Only a select few see the dark signs: Amanda, the town psychiatrist, and the local newspaper publisher. Together, they set out to discover exactly what’s happening in Port Isley — and whether or not anyone has a prayer of getting out of the town alive.
