Return of the Mummy (Classic Goosebumps #18)

After last year's scary adventure, Gabe's a little nervous about being back in Egypt. Back near the ancient pyramids. Back where he saw all those creepy mummies.
Then he learns about an Egyptian superstition. A secret chant that is supposed to bring mummies back to life. Gabe's uncle says it's just a hoax.
But now it sounds like something's moving in the mummy's tomb.
No way a couple of dumb words can wake the dead.
Can they?
