This sequel to Wizard's Bane picks up after Wiz's victory of the Dark League. The remnants of the Dark League want William Irving "Wiz" Zumwalt, computer programmer and worker of magic, dead and there are wizards who wish his changing of the laws of magic were put an end to. Wiz begins work to write a new magic "compiler" which will help to end the abuses of magic that followed his discovery of magical "programming," but when he suddenly (and mysteriously) disappears someone needs to finish his work. And so his wife and confidant Moira journeys to Earth to recruit a batch of computer specialist for a "secret project."
