It's a well-researched book and the author almost has me convinced that the experiences and people of L. Frank Baum's life make up the story of the The Wonderful Wizard of Oz. But if I choose to believe this all as absolute fact, then the story will lose its magic for me, becoming just a vehicle by which Baum spewed his "spiritual awakenings" and other theosophical mumbo jumbo of which I do not agree. The history in this book is quite interesting in places, more than Baum himself. I come away from this book with a slightly less favorable impression of L. Frank Baum. And that is my regret in having read it.
