Have you ever known a genius? A real, flesh and blood hunk of mental brilliance with a one-tracked mind, a gambling habit, and not an ounce of common sense? Meet Xando Pri, five-thousand years into the future. For almost twenty-five Terran years, Xando has planned to escape his politically powerful "Father", Tobal Pri, the man he was genetically engineered for. On the verge of escape, Xando runs into some extra-universal interference.
When a gigantic copy of an ancient sumo wrestler appears, Xando cannot refuse the challenge of learning why the strange being has come, and what is hidden in that alien intelligence.

The eccentric Terran genius does not know that the alien has been sent into the universe on a deadly mission, one that could destroy the Tau-Gamma Universe. The massive alien has suffered a lapse of memory. Will the alien remember why he was created by the Masters and what he must do? Will Xando be able to stop him?
