Query: Disappointing

I waited the 4 weeks it took to get this book and I cannot express how poorly written it is. There are many good books on Crane, but this one is defintely to be avoided. The author is supposed to be a Crane expert but he cannot explain anything clearly. In fact, he seems angry about having to write this book for a living. Avoid this one.
