The Mummy Walks
R. L. Stine
(Rebound by Sagebrush, April 15, 1999)
Michael may look like a regular kid, but he's really the leader of a country called Jezekiah, and he's got a computer chip in his head that carries the secret location of an ancient mummy. There's just one problem. Michael doesn't know he's a prince. And his people want their mummy back.
