Bioshock: Rapture by John Shirley

Combination video game novelization and dystopian parody of Atlas Shrugged in which a new civilization is built that doesn't turn out quite as awesome as expected.

This book is a prequel to the BioShock video games, which I have not played.  It begins with wealthy capitalist, Andrew Ryan, recruiting people to populate his wonderful, new, underwater, capitalist paradise called Rapture and apparently bridges the descent of Rapture from perfect society to the setting of the horror games.

Warning, some spoilers will follow.
