Glinda and Dorothy travel to an obscure corner of Oz to prevent a war between the Skeezers and the Flatheads. When the Skeezers imprison them on a glass-covered island at the bottom of a lake, Glinda and Dorothy must call upon their magical friends to rescue them.
The last of the original Oz books written by L. Frank Baum, this story was dedicated to his son, Robert.
