Earl Jenkins, a downsized tech, accidentally blasts himself from 2024 Phoenix to 1957 Iowa using a homemade dimensional hopper. Stranded, he poses as a handyman, but discovers the small town harbors a dark secret: a fanatical preacher, "the Gardener," is using stolen technology to enforce a single, "pure" timeline. To get home, Earl must outwit this ruthless guardian of reality, using his knack for repair, a quantum cat, and the clues from a lost genius's journal—all while surviving church potlucks and the perils of a paradox.
