Dear Boys and Girls:What could be more interesting than an Oz mystery? What, indeed? "Why," I can almost hear you shout, "Two Oz mysteries." And here you have them in this newest Oz story, two very mysterious mysteries to solve and ponder over and so many new Kingdoms and characters, I can hardly remember the proper spelling for their names.You will be glad to know that Dorothy has most of the strange adventures in this book and remember Pigasus? Well, I have long suspected Pigasus could be useful as well as poetical, and now that he has so convincingly proved his prowess (how do you like THAT word?) we'll have to treat him with more respect and dignity.Your letters all year have been grand and if I had the magic necklace mentioned in this story I would wish you three hundred and sixty-five days of happiness.But after all, I HAVE a magic necklace. Each boy or girl who reads the Oz books is one shining link in the friendly chain that holds us together. All friends and all for Oz.You believe in Oz and I'll believe in YOUHo, that's the stuff that's strong enoughTo make my wish come true.So, happy year to you, dears. And next year? Ah well, who knows what will happen next year? Another Oz book maybe, if you still want one. Write me if you do, and best of everything wonderful to you all, always!
