Conquering the Impossible: my 12,000-mile Journey Around the Arctic Circle, by Mike Horn

This guy is pretty crazy! The book starts out shortly after Mike is done with his last crazy journey, which was to circumnavigate the globe around the equator. He did this on foot and in a sailboat. He decides to do this same thing around the Arctic Circle, but has no prior arctic experience whatsoever, so he hooks up with 2 people who are planning to cross Greenland by foot and after a few days they are stuck in their tents for 2 weeks because of horrendous weather and they give up on the project. Mike Horn decides he's now got enough experience to do a warm-up journey before the big one around the circle. How about a solo journey from the northernmost tip of Europe to the North Pole? With his (very little) experience he does go off on his next adventure towards the North Pole and on it he manages to get frostbite on the ends of all his fingers which ultimately makes him cancel the rest of the trip and get rescued. Back in civilization the doctors cut off the last joint of most of his fingers and thumbs and tell him he needs 2 full years of healing before he should expose his damaged fingers to extreme cold so what does he do? He plans and takes off on his trip around the Arctic Circle 4 months later. It's actually a well written and amusingly entertaining book about a guy with an amazing amount of drive.
