Query: Great resource book!

First let me say - I have read this book and think it is excellent. It is helpful to me as a sponsor and as a sponsee. The first part talks about what sponsorship is about and also what it isn't. The first half of the book is for someone looking for a sponsor and what they should look for. The second half of the book is for Sponsors and has some good guidelines for being a sponsor culled from the experience and wisdom of numerous people besides just the author. I was a little skeptical at first because it is not AA literature, but it is a Hazledon book which is acceptable. Being a sponsor in AA is not a professional role, so having a book like this can be helpful because what most people know about being a sponsor they learned from their sponsor. As AA as a community continues to evolve and grow, and old timers die, it's good to have additional wisdom for guidance. This is just my opinion, I do not speak for AA.
