Dorothy and the Wizard in Oz, by L. Frank Baum (a review by Calvin)

Yes we are clearly making our way through the entire catalogue of Oz books. Dorothy and the Wizard in Oz is the fourth book in the sequence and so far each subsequent book is at least as good as the last.  I've sung praises for the series often enough already that I think no more need be said, so I'll just move right into Calvin's review.
