Query: Great Book

Be advised once you get into this book its hard to get out. While a few chapters of this 500 page brick were highly unessisary the book was incredibly good. I beg to differ with the reviewers who said the book was too preachy. While it did include a trac like christian message it was weaved into the book and hardly noticable (if you skip a few paragraphs).
