I read Oz books to my children until there weren't any left. My daughter, in particular, would ask questions about the nature of magic in Oz that needed to be answered.In answering them, I began to write my own sequels to the works of L. Frank Baum. I was always impressed with the strength of the characterizations of woman by Baum and later learned that he was the son-in-law of Matilda Gage, one of the leaders of the woman's movement in the early 20th century.
