John Rayburn thought all of his problems were the mundane ones of an Ohio farm boy in his last year in high school. Then his doppelgänger appeared, tempted him with a device that let him travel across worlds, and stole his life from him. John soon finds himself caroming through universes, unable to return home – the device is broken. John settles in a new universe to unravel its secrets and fix it.
Meanwhile, his doppelgänger tries to exploit the commercial technology he's stolen from other Earths: the Rubik's Cube! John's attempts to lie low in his new universe backfire when he inadvertently introduces pinball. It becomes a huge success. Both actions draw the notice of other, more dangerous travelers, who are exploiting worlds for ominous purposes. Fast-paced and exciting, this is SF adventure at its best from a rising star.
