First let me say that I really enjoyed this book. It was fun and witty, and interesting. It was more philosophical and political than I expected, but there was also plenty of plot. It was thoroughly enjoyable.
I must also say that it wasn’t quite what I expected. I’ve seen the musical, and I expected a longer, more detailed version of that story. I remember reasoning from the musical, such as how Elphaba and Galinda became friends, and the role Fiyero played between them, and Elphaba’s beef with the Wizard, and how the scarecrow, tin man, and cowardly lion fit in. It all made sense, but it was all different from the book. The musical is as if they took the barest bones of the book, the idea that the Wizard is actually the bad guy, and Elphaba was trying to effect social change in Oz, and applied it, and a few other things, but really it’s very different. Different good, but different.
I’m not going to go into detail here (to avoid spoilers), but I was disappointed with the ending. I wanted things to work out differently for many of the characters, and I didn’t like the open endedness that left room for the sequel. Basically, the book started out great, and went downhill from there. But it was good.
