Jack Meter has taken care of Annie’s murderer and saved the universe. He’s beginning to feel better about life in general when Peter Winston, lawyer and friend, brings him a potential client. Lambert Garner, a rich eccentric developer, claims one of his buildings has disappeared into thin air, and he wants Jack to find it. Jack thinks Garner is a nutcase until he goes to the building site and gets a tickle from his telecarb, the world-hopping device the Thrittene can"t seem to be able to remove from his wrist. Soon, Jack discovers that there’s more to space than he first thought, and now it’s all bleeding together, destabilizing the cosmos. It"s possible to travel from one parallel universe to the other –if one has the right equipment, something Neola Durwin, a sexy intergalactic agent, possesses. But it"s not only universes merging that worries Neola—someone is stealing pieces of them, just like they stole Garner"s building. Jack teams up with Neola to find out why cosmic real estate is disappearing, where it’s disappearing to and who is responsible. The road takes a sharp turn when he comes face-to-face with his exact double from another universe. Is the other Jack involved in the thefts? Who are his accomplices? And in the end, which of the two Jacks will remain standing?
