Cube Rube — Scott Michael Decker

After salvager Jack Carson arrives to the capital of the long-dead Circian Empire, he finds a ghost cube that tells him he's been chosen to become the next Emperor.

Even though he finds this ludicrous, Jack teams up with an orphan girl who claims to be the Princess of Circia. Troubled by divorces, bankruptcies and his constant search for smoke-induced oblivion, Jack tries to figure out what's going on while avoiding debt collection agents sent by his ex-wife.

Through a series of escapades, Jack finds out more about himself than he thought possible. But who is the mysterious girl, and could the Cube be right?
