Magic Tree House
Junie B. Jones
Two girls: Best friends Hattie and Delores feel that life in their small New Hampshire town is a dead end.
One horse: Old and about to be put down, Speed gets a reprieve when Hattie and Delores decide to save him.
A road trip: Determined to set Speed free, Hattie and Delores drive him west in search of rangeland. But the road takes some unexpected turns as the girls get their own taste of freedom—and as they confront the reasons they left home.
