Codespell

The universe needs a reboot in this WebMage novel from Kelly McCullough.
In the twenty-first century, magic has advanced with the times and gone digital, and Ravirn, a direct descendant of one of the three Fates, is a talented sorcerer—and  computer hacker extraordinaire. Now that Ravirn has come into his own as a minor chaos power, he’s partying with Zeus, playing hard-to-get with a gorgeous Fury…and trying to stay one step ahead of Nemesis, the unstoppable goddess of vengeance.
 
But now Necessity—the sentient computer that runs the universe—has caught a virus that crashes most of the magical internet, and Ravirn is tasked with fixing it. And Ravirn hasn’t missed the fact that whoever repairs Necessity will, for that moment, run the universe, able to remake the worlds (and everything else) to their liking.
 
Unfortunately for Ravirn, some very dangerous beings have figured that out, too…
