Well researched, well written. Very detailed, especially in the latter part of the book. The chapters on the War are absolutely horrific and illuminate the development of the character and mind set of the men that set off into the unknown in Asia. Doesn't explain the modern people that still climb Everest, though. It is truly amazing that those men were able to achieve what they did with the technology and equipment they had available to them. An enjoyable read and an interesting thesis, though I found myself skipping over much of the minute detail of the treks into the mountains. For anyone interested in George Mallory and Everest, this is an illuminating read.
