Query: Good book

The book is being used in a small group study. It is working out great. I was happy to find the book at a great price and received it short time in almost like new condition (only a few pencil marks). We have only completed the first chapter, but the material has led toward interesting discussion. I look forward to learning and completing the material, but the book has already been well worth the price.
