Ozma of Oz is the third in the Oz series, but, as is generally the case with the Oz books, it’s not that important to read them in order, especially when it comes to the first few. This one harkens back to some earlier events and brings up characters who are introduced in the second book in the series (The Marvelous Land of Oz) but if you’re familiar with the Wizard of Oz, you’ll have no problem picking up on the plot. Dorothy Gale has returned to Kansas and is headed on a voyage to Australia with her ailing uncle. As befits our disaster-prone heroine, the ship hits a storm and Dorothy is swept overboard. When she wakes up, she finds herself in a strange land with a talking hen named Bill, and is quickly caught up in an adventure to rescue the kidnapped royalty of this new world (the land of Ev) that involves some familiar faces (the Scarecrow, the Tinman, the Lion) and some new ones (a thinking/talking/walking robot, Queen Ozma of Oz, and the evil Nome King, among others).
