WebMage

Magic gets an upgrade in the first WebMage novel featuring a computer savvy sorcerer... Ravirn is not your average computer geek. A child of the Fates-literally-he's a hacker extraordinaire who can zero in on the fatal flaw in any program. Now that twenty-first-century magic has gone digital that makes him a very talented sorcerer. But a world of problems is about to be downloaded on Ravirn-who's just trying to pass his college midterms.
Great Aunt Atropos, one of the three Fates, decides that humans having free will is really overrated and plans to rid herself of the annoyance-by coding a spell into the Fate Core, the server that rules destiny. As a hacker, Ravirn is a big believer in free will, and when he not only refuses to debug her spell but actively opposes her, all hell breaks loose. Even with the help of his familiar Melchior, a sexy sorceress (who's also a mean programmer), and the webgoblin underground, it's going to be a close call...
