Off to Be the Wizard Audiobook (Free)

An io9 Can’t Miss Research Fiction and Fantasy name in March 2014.

Martin Banks is just a regular guy that has produced an abnormal discovery: he may manipulate reality, because of reality being only a computer plan. With every use of this ability, though, Martin discovers his small “tweaks” have not escaped notice. Rather than encounter prosecution, he decides instead to travel back in its history to the Middle Ages and pose being a wizard.

What could possibly go wrong?

An American hacker in King Arthur’s court, Martin must now train to become full-fledged master of his powers, uncover the truth behind the historic wizard Merlin…and not, y’know, die or anything.
