Daniel Eakins inherits a belt from his uncle that allows him to travel in time. This results in a series of time paradoxes, which are only resolved by the existence of multiple universes and multiple histories. Eakins, who repeatedly encounters alternate versions of himself, finds himself in progressively more bizarre situations. Much of the book deals with the psychological, physical, and personal challenges that manifest when time travel is possible for a single individual at the touch of a button. Eakins repeatedly meets himself; has sex with himself; and ultimately cohabitates with an opposite-sex version of himself. He spends much of his own contorted lifetime at an extended party with dozens of versions of himself at different ages, before understanding the true nature of the gathering, and his true identity.
