The Wonderful Wizard of Oz & Glinda of Oz

In The Wonderful Wizard of Oz, a huge cyclone transports the orphan Dorothy and her little dog Toto from Kansas to the Land of Oz, and she fears that she will never see Aunt Em and Uncle Henry ever again. But she meets the Munchkins, and they tell her to follow the Yellow Brick Road to the Emerald City where the Wonderful Wizard of Oz will grant any wish. On the way, she meets the brainless Scarecrow, the Tin Woodman and the Cowardly Lion. The four friends set off to seek their heart's desires, and in a series of actionpacked adventures they encounter a deadly poppy field, fierce animals, flying monkeys, a wicked witch, a good witch, and the Mighty Oz himself.

In Glinda of Oz, the last of the original ‘Oz’ books, Dorothy and Princess Ozma seek the help of Glinda, the Good Witch of the South, when they find themselves in peril on the Magic Isle of the Skeezers
