Synopsis: Q: How does a shanghaied computer geek conquer all the forces of Darkness and win the love of the most beautiful witch in the world?

A: By transforming himself from a demon programmer into a programmer of demons!

It all began when the wizards of the White League were under attack by their opponents of the Black League and one of their most powerful members cast a spell to bring forth a mighty wizard to aid their cause. What the spell delivered was master hacker Walter Wiz Zumwalt. The wizard who east the spell was dead and nobody -- not the elves, not the dwarves, not even the dragons -- could figure out what the shanghaied computer nerd was good for.But spells are a lot like computer programs, and, in spite of the Wiz's unprepossessing appearance, he was going to defeat the all-powerful Black League, win the love of a beautiful red-haired witch, and prove that when it comes to spells and sorcery, nobody but nobody can beat a Silicon Valley computer geek.
