Going Postal by Terry Pratchett
Moist von Lipwig, con man extraordinaire who unfortunately got caught, narrowly avoids dying...only to be practically forced into becoming Postmaster at the long-defunct Post Office of Anhk-Morpork. The task is, well, impossible - he has only two employees and a golem for a parole officer to make sure he stays in line. The Post Office has bigger problems than that, though, with its mail bursting out of every room and everyone using the Grand Trunk to send messages. Maybe it's a perfect job for a con man, after all.
Though the 30th in the Discworld series, you don't need to have read any of the others to enjoy the story (I've only read one other one that had nothing at all to do with this). Pratchett's trademark humor made me laugh out loud at times, and Stephen Briggs did an excellent job narrating. 4.5 stars.
