I have...following Keeper's advice ...And I have to say it was one or the most amazing book I've read so far, it is intriguing, exciting and some of the facts were kind of new to me...I have lent it to a friend and she felt exactly the same, she called me to thank me and wanting to discuss it...While I was reading it, I felt like discussing it with everyone and/or advising them to buy it as well...I'd love my mum to read it but she doesn't speak a word of English and I'm trying to see if I can find the Spanish version...I'm about to read another of his books but I am not sure it will have the same effect...Thanks Keeper!!!
