The author Nick Page spoke at a Church retreat I attended recently and I was really impressed with his ability to get across the key messages and themes of the Bible. I subsequently bought this book for myself and a copy for a friend. A few days in and I'm totally engrossed. As the other reviewer comments, this is a book which should appeal to Christians and non-Christians alike. For me, it's bringing a new understanding of the crucifixion story and it is helping me to better understand why Jesus spoke and acted as he did. Not only is this book incredibly helpful, it's a fascinating historical read.
I also bought The Big Story The Big Story which Nick's Church talk was based upon. A much lighter and funnier touch than The Longest Week, but well worth a read for anyone who could do with a bit of perspective on the Bible story.
