After hearing a presentation by Rabbi Cahn, I decided to purchase this book and subsequently read it on a trip with my daughter. (She was driving; I was reading.) Totally captivating but was truly surprised it was written in a fictional genre. We both were so anxious to finish it, we sat in the driveway for an additional period of time to complete the book even after we returned home from our trip. It's a fascinating read, but our interest grew in the factual content and so we went on to read "The Mystery of the Shemitah" by this author. Very worthwhile for both books!
