Eric is the Discworld's
only demonology hacker.
Pity he's not very good at it.
All he wants is three wishes granted. Nothing fancy - to be immortal,
rule the world, have the most beautiful woman in the world fall
madly in love with him, the usual stuff.
But instead of a tractable demon, he calls up Rincewind, probably
the most incompetent wizard in the universe, and the extremely intractable
and hostile form of travel accessory known as the Luggage.
With them on his side, Eric's in for a ride through space and time
that is bound to make him wish (quite fervently) again - this time
that he'd never been born.
