From the publisher:
Swallowed up by an earthquake on their way to Hugson's Ranch, Dorothy and her cousin Zeb find themselves trapped in the magical and magnificent fairy lands that lie just beneath the Earth's surface. With the wonderful Wizard for company, the cousins' journey to the Emerald City is beset by invisible bears, dragons, gargoyles and...vegetables? Will they ever find their way back to the surface world where they belong?
