The reason I can't give it a 10, is the editing. I have never seen a book of this quality (or even of considerably lesser quality) with this many mistakes and typos! As Jerry Kratochvil (previous review) stated, the flow of the text was interrupted by the "sidebar" articles, and while I did know the word "cwm" I assume most wouldn't, and they didn't give the definition/explanation of it until it had already been used several times. The book is beautifully laid out from a visual standpoint, but it seems like no editor actually read through it.
Still, I can't recommend the book enough! And for much more about the story, including lots of great stuff including breathtaking QTVR images (the one from the summit is beyond words!)
