"In the twenty-first century, magic has advanced with the times and gone digital. Ravirn--umpteenth great-grandson of one of the three Fates--is a talented sorcerer, a computer hacker extraordinaire, and in the process of becoming a minor demigod. His best friend and familiar is both a goblin and a laptop, changing from one shape to the other as needed. While repairing Necessity (the badly broken sentient computer that runs the multiverse), Ravirn is thrown into a very different place: a parallel world where the Greek gods are only myths. This strange realm is ruled by the Norse pantheon--Odin, Thor, and other fun-loving brutes--and their magic uses a completely different operating system. A system that Ravirn will have to hack if he ever wants to get out of Asgard alive..."--p. [4] of cover.
