He's the perfect starship trooper: big, strong, and not too bright. He's the perfect hero: willing to do almost anything to save his neck (it's one of the body parts that's still his own).

Tsuris, the Mystery Planet, has a mysterious secret weapon, and Bill must get it. But Bill has something the Tsurisians want. They have a lot of brains, but not enough bodies. They'll take any body that comes along--and put one' of their brains in it!

Can Bill escape with his own brain? Can he find the secret weapon? Can he get a drink?

Harry Harrison, the best-selling author of WEST OF EDEN and THE STAINLESS STEEL RAT, teams up with Robert Sheckley, acclaimed author of THE TENTH VICTIM, to send Bill, the galactic hero, through time, space, and sobriety.
