Why would the Wonderful Wizard of Oz leave that magical land and head back to the monotony of the Great Outside World? Well, don't expect to find any compelling reasons why in this "Oz" book. In fact, that is just one of many plot points that just don't add up. Not to say the book doesn't have a few good ideas; it does. Unfortunately they are drowned out in histories and characters that simply just can't be reconciled with the Oz Baum created and was perpetuated by Thompson, Neill, Snow, etc.
The main character, a young boy named Jamie, is really none too spectacular. Yet he is the one destined to become "Oz the Magnificent" after attending "Magic Club" meetings in the basement of the local library. The stunts he performs are supposedly masterful, yet any kid could learn the same tricks from a magician kit purchased out of a Sear's catalogue. And the author makes sure you know these are not "tricks" but "sleight of hand". The later phrase is only a fancy way of saying "deception", which is, simply put, trickery. Oscar Diggs started out just like that...a glorified balloonist/stage magician/ventriloquist. He did not learn to actually produce true magic until many years of tutelage under Glinda the Good. Yet Jamie just waltzes into Oz and takes up the mantle of Oscar in no time flat.
The book begins with Jamie's parents pulling out an old humpback trunk that had belonged to Oscar Diggs (the Wizard of Oz) who is supposedly Jamie's great-grandfather. Just like that, only a few paragraphs into the story, and it's already gone into left field. Oscar digs never left Oz to come back to America permanently, neither did he marry, and (despite what this story claims) neither did he die. Perhaps this could have worked if Jamie was Oscar's great-nephew. A far more plausible plot point and one many more Oz readers would accept. And one must beg the question that if Oscar were indeed a famous ancestor than why wouldn't Jamie's parents not have told him long before now, and why wouldn't he know a heck of a lot more about Oz?
Speaking of Jamie's parents, it's not hard to surmise that they are supposed to be an idealized version of a modern family. This might have worked if they had been developed better. The mother, and especially the father, seem very wooden and void of any tangible personality. It becomes tedious after the first few chapters, and the family activities are of very little interest.
After several non-descript chapters, Jamie arrives in Oz, the means of which hearken back to Baum's The Road to Oz, which is very imaginative. The first characters he encounters are several members of the Oz menagerie. The author handles them fairly well, but slips up in his description of Bungle the Glass Cat. This is only one of many, many discrepancies that are to follow. And they are very glaring indeed. So much so that it makes the story even harder to read.
Ozma is said by the author to have looked into her "Magic Mirror" to see Jamie before he came to Oz. It is stated over and over in Baum's Oz books that Ozma views her friends and subjects in a Magic Picture, a blank canvas that paints the person she wishes to see. Glinda's great Book of Records is an extremely large book that is chained to a marble table, yet the author has Glinda carry it around like a paperback novel. The Tin Woodsman's castle is said to be made of silver in this book, yet it is supposed to be made of tin, just like its owner.
And poor Dorothy, hungry for the companionship of a friend; never mind she has her two girlfriends Trot and Betsy Bobbin from America, not to mention Button Bright who has been with her for several decades, and her greatest friend of all, Ozma herself. So simple is Dorothy that when Jamie takes a coin and flips it across his knuckles, she squeals "with delight". Dorothy has traveled to Oz via cyclone, stormy seas, and an earthquake. She has witnessed Glinda the Good, the Wizard of Oz, Ozma, and others perform wondrous feats of true, supernatural magic yet a simple amateurish sleight of hand gets her giddy. It just doesn't jibe with her character at all.
And that is the main ingredient that this whole book lacks: magic. Jamie learns that by simply saying "Wham, Bam, Alikazam" he can cast any sort of spell he wants with no true training or any previous exposure to how Oz magic works. And the long lost magic words used by the Wizard ("Hocus, Pocus, Dominocus") makes the true Magician of Oz's abilities seem far too basic. Such simplistic magic phrases are better left to Bugs Bunny and Count Bloodcount. If only I could say "Abra-ca-pocus" and make this little ditty disappear...
