This book follows a small group of adults as they explore C.S Lewis's case for Christ. Each has a different view and they are stereotyped pretty typically here. I just didn't like the set up of the book and felt the "discussion" of the group was always set in a formula - each had their role to play and arguement to make. In the end, the format of the book didn't really add anything and didn't give much insight into the Lewis case. Check out Mere Christianity and get it straight from Lewis if you are interested.
