The Magic Hat of Mortimer Wintergreen

In 1890s South Dakota, Amy and Joshua escape from their mean aunt Vootch. They plan to find their grandparents in New York and manage to team up with a traveling magician, Mortimer Wintergreen, who is also New York bound. Mortimer owns a truly magic hat with a temperamental, mischievous mind of its own.

Adventures abound as their way is blocked by outlaws, runaway hot-air balloons, geese, and the persistent Aunt Vootch¿but the hat is always ready for action.
