The fact and fiction blend of Magic Tree House meets the wacky characters of Junie B. Jones, the irreverance of Captain Underpants, and the science fun of the Magic School Bus! This is the first book in a four-book set that takes the kids on a tour of the Earth's history, from the planet's formation to the extinction of the dinosaurs, as they try to rescue their uncle Al and find their way home.
The evil Dr. Kron-Tox has kidnapped Uncle Al and whisked him away in his time machine! Luckily, Andrew has a time machine of his own. But like most of Andrew’s inventions, the Time-a-Tron doesn’t work quite right. It tumbles Andrew, Judy, and Thudd back to the very beginning of the universe! Will they regain control of the Time-a-Tron in time to save Uncle Al . . . and themselves?
