Rinkitink in Oz, by L. Frank Baum (a review by Calvin)

Fun, imaginitive, a bit of good vs. evil with good winning the fight, Rinkitink in Oz is a standard Baum fairy story, but the only reason it's an Oz book is that Dorothy and the Wizard make a cameo appearance in the last chapter or so, and the new Nome King, too. I think Calvin missed our old friends, but he's so captivated by these books in general that I'm not sure he remembered he missed them until they showed up at the end. Another Baum that gets an A+ from us.
