Fleeing the city of New York on the TransContinental atmospheric transport vehicle, Dran Florrian is traveling with Palimpsest-the ultimate proof of a lifetime of scientific theorizing. When a rogue organization attempts to steal the device, however, Dran takes drastic action. But his invention threatens to destroy the very fabric of this and all other possible universes, unless Dran-or someone very much like him-can shut down the machine and reverse the process.
