If anyone is looking for the perfect adventure story to read this summer, try Alfred Lansing's 1959 classic (the 1999 2nd edition is widely available) Endurance: Shackleton's Incredible Voyage.
It is an absolutely fascinating account of the 1914 Imperial Trans-Antarctic Expedition that went horribly wrong. Lansing wrote the book after interviewing and researching diaries of the majority of the expedition's members. It's a tough one to put down.
“For scientific discovery, give me Scott. For speed and efficiency of travel, give me Amundsen. But when disaster strikes and all hope is lost, get down on your knees and pray for Shackleton.”
–Sir Raymond Priestley
