I have read a lot of Jeffery Archer over the years, and while he may not be every one's cup of tea he is a pretty good read. This followed on from my previous reads about great mountaineering adventures.
Paths of Glory is fiction, but based on the true story of George Mallory's life and the early, unsuccessful, Everest expeditions in the 1920's
