A space-faring ne’er-do-well with more bravado than brains, Rex Nihilo plies the known universe in a tireless quest for his own personal gain. But when he fleeces a wealthy weapons dealer in a high-stakes poker game, he ends up winning a worthless planet…and owing an outstanding debt more vast than space itself!

The only way for Rex to escape a lifetime of torture on the prison world Gulagatraz is to score a big payday by pulling off his biggest scam. But getting mixed up in the struggle between the tyrannical Malarchian Empire and the plucky rebels of the Revolting Front―and trying to double-cross them both―may be his biggest mistake. Luckily for Rex, his frustrated but faithful robot sidekick has the cyber-smarts to deal with buxom bounty hunters, pudgy princesses, overbearing overlords, and interstellar evangelists…while still keeping Rex’s martini glass filled.
