I wasn't so struck on this book. I am not a mountaineer but I have recently enjoyed reading of mountaineering adventures on Everest. I thought I'd enjoy hearing about K2 as well, but I found that many sections in this book seemed to be little more than lists of obscure names and dates and geographical places. This may mean something to climbing enthusiasts (who know K2 and its environs) but for me this made the book rather unreadable.
A good history of the conquering of K2, probably interesting for research, but it lacked the detail and excitement for a "lay" reader such as myself!
