Something was happening in Bobbi Anderson’s idyllic small town of Haven, Maine. Something that gave every man, woman, and child in Haven powers far beyond those of ordinary mortals. Something that turned the town into a deathtrap for all outsiders. Something that is buried in the woods behind Bobbi’s house. With the help of her friend, Jim Gardener, they uncover an alien spaceship. And as they learn more about this strange discovery, the citizens of Haven begin to change: The townspeople are being welded into one organic, homicidal, and fearsomely brilliant entity in thrall to the Tommyknockers, who piloted the alien ship.
