Query: Lacking

You may want to read this book, most likely because of your familiarity with his other pieces. You may know he is a very talented writer. This book lacks all of the direction and coherence that Wicked offered, however, and comes off as a confusing plumb-the-depths-of-whatever-soul Bildungsroman. I was surprised at how much I enjoyed Wicked and how little I enjoyed this. Alas.
