Zany Circus: Pythagoras Rules (Paperback) (ISBN-13: 9780648130161)

Zandee, Tobelia, and Kadin Zany live in a circus, don't go to school, and have a habit of wreaking historical havoc.

With the help (and hindrance) of the world's lamest math-magician, a high-voltage stalker, two quirky cousins, and a whole lot of moths, the Zany Circus kids must prevent the destruction of the universe, and occasionally remember to feed Random Goat.

Is Grannie really a vampire? Did Dad eat a sock in a salmon sandwich? Will Pythagoras die in a field of beans?

Yes.

Wait... what happened to history?
