I first read this book when I was about 15 and loved it, so when I saw it again I really wanted to read it. Unfortunately it did not have the same impact on me this time round. Obviously the book hasn't changed so it must be me. I found it rather tedious in parts even though the subject matter should be one of the most fascinating possible. I felt that the writer made some sweeping conclusions and presented them as fact. The biggest disappointment to me was, I still don't know who moved the stone....did I miss something ?
