Codespell (Ravirn, Book 3)

The universe needs a reboot...

In the twenty-first century magic has gone digital, and Ravirn, a direct descendant of one of the three Fates, is a talented sorcerer and computer hacker extraordinaire. So when Necessity, the sentient computer that runs the universe, catches a virus that crashes most of the magical Internet, Ravirn is tasked with fixing it. Whoever repairs Necessity will, for that moment, run the universe. Unfortunately for the sorcerer, some very dangerous beings have figured that out too.
