4.5 Mind Altering markl72 | 31/07/2007 | See all markl72's reviews (9) I picked this book up before I went on holiday this year and almost didn't read it. I'm so glad I did! I started it at 8.30 in the evening and only stopped reading it at 1.30 in the morning when I had completed it!! I just couldn't stop reading it. I have never read anything quite like this before and the author has a real gift in being able to tell the story in the way that he did. It really blew my mind away in parts - not that there's much to blow away I'll admit - and I was baffled at how much research was needed for some of the diagrams etc. This is a real gem of a book well worth the time!
