I was a bit disappointed with the SEA FAIRIES, Baum's first book to introduce the characters of Trot and Cap'n Bill. It was adequate but not up to the superlative quality I expect from L. Frank Baum. This book, however, sets things to right. It reads more like the Oz books and even includes characters such as Button Bright and Polychrome who make numerous appearances in the Oz series. It is a fun book that I enjoyed even with my youth far behind me.
In this story, Trot meets Button Bright who has a magical umbrella which takes him where he wants to go. Trot, Button Bright and Cap'n Bill decide to use the umbrella to take them for a picnic out on an island just off the coast. Instead of being taken to that island, however, they wind up on and island in the sky inhabited by tow warring peoples. Our characters wind up in the middle and have to set everyone straight.
It is a delightful tale which should appeal to both boys and girls.
