"You've heard of Faust ... this is Eric. There's a difference. Eric is fourteen, lives on the famed and magical Discworld, and is the first ever demonology hacker. Fortunately, he doesn't succeed in raising any devils, but he does raise Rincewind (the most incompetent wizard in the universe) and the Luggage...
(the world's most dangerous travel accessory). When Eric turns them loose on an unprotected world, the idea is that Rincewind will grant him his three rather adolescent wishes.
You know, the usual three - live forever, rule the world, meet the most beautiful woman who ever lived. Simple, really. Getting marooned at the dawn of Time, changing the future and meeting history's most embarrassing god is only the start.
Creating life on the Discworld is a mere detail. Because Rincewind ends up going through Hell. Literally."
