The Game-Players of Titan

In this sardonically funny gem of speculative fiction, Philip K. Dick creates a novel that manages to be simultaneously unpredictable and perversely logical.
Poor Pete Garden has just lost Berkeley. He's also lost his wife, but he'll get a new one as soon as he rolls a three. It's all part of the rules of Bluff, the game that's become a blinding obsession for the last inhabitants of the planet Earth. But the rules are about to change--drastically and terminally--because Pete Garden will be playing his next game against an opponent who isn't even human, for stakes that are a lot higher than Berkeley.
