Seeing ghosts has plagued Dumdie Swartz since early childhood. Afraid that ghost guts might stick to her if she stepped through them, thirteen-year-old Dumdie Swartz still cringes when she encounters them. Her strange attempts to avoid spirits create a lonely life. Her sisters constantly mock her strange behavior, her parents are clueless, and her social life is zero.
Dumdie finds solace working in a shared garden with her elderly neighbor, Mr. Carson. When teens from her high school steal pumpkins from his garden, Mr. Carson is hurt during the theft, and later, dies. Dumdie’s life takes a dark turn. She learns there are stranger things than ghosts, when she senses something evil living in Kyle, one of the boys who had raided the pumpkin patch.
Kyle bullies Dumdie to scare her into silence. The more Kyle threatens her, the clearer she perceives the evil thing possessing him. Dumdie finds support in an unlikely group of girls who befriend her when she helps them with their costumes for the Pumpkin festival. During the festival, Dumdie’s fears explode when the thing possessing Kyle decides it wants to possess her.
