The first novel from Caustic Critic Ben "Yahtzee" Croshaw, famous for his online Video Game critque series Zero Punctuation, introduces us to the world within a popular Fantasy-themed online MMORPG (basically World of Warcraft in all but name). There, the NPCs go about their daily lives, unaware that some of the people among them - thought to suffer from a strange syndrome - are player characters controlled by beings from another universe: us.
