The Emerald City of Oz

by L. Frank (Lyman Frank) Baum

"The Emerald City of Oz" by L. Frank Baum is a novel published in 1910. Dorothy Gale brings her Aunt Em and Uncle Henry to live permanently in Oz, escaping financial ruin on their Kansas farm. While they tour the magical land, the vengeful Nome King assembles a fearsome alliance to invade Oz and reclaim his stolen Magic Belt. This sixth Oz book weaves together two parallel stories—one of wonder and discovery, the other of impending danger—as Dorothy's peaceful new life faces its greatest threat.
