My favourite so far has been Endurance: Shackleton's Incredible Voyage about Shakleton's semi-doomed voyage to Antarctica where they survived an entire winter after their boat got stranded in ice. Mostly by eating seals... and their sled dogs at one point.
"It tells the story of the British explorer Percy Fawcett who, in 1925, disappeared with his son in the Amazon while looking for an ancient lost city. For decades, explorers and scientists have tried to find evidence of his party and the Lost City of Z. Perhaps as many as 100 people perished or disappeared searching for Fawcett over the years. Grann made his own journey into the Amazon, revealing new evidence about how Fawcett died and showing that Z may have really existed right under his feet." 
Also, The Man Who Ate His Boots which covers some of Franklin's earlier overland exploration.
