Eric, Terry Pratchett
Number 9 in the Discworld series, ERIC is the story of the Discworld's only demonology hacker. Of course the Discworld has a demonology hacker, and of course he wants to be master of the universe, and of course he's hopeless at getting his own way.
And the Luggage makes it's first appearance. What's not to love.
Discworld's only demonology hacker, Eric, is about to make life very difficult for the rest of Ankh-Morpork's denizens. This would-be Faust is very bad...at his work, that is. All he wants is to fulfill three little wishes:to live forever, to be master of the universe, and to have a stylin' hot babe.
But Eric isn't even good at getting his own way. Instead of a powerful demon, he conjures, well, Rincewind, a wizard whose incompetence is matched only by Eric's. And as if that wasn't bad enough, that lovable travel accessory the Luggage has arrived, too. Accompanied by his best friends, there's only one thing Eric wishes now -- that he'd never been born!
