If you ever thought, "Sure, Aron Rolston is tough, but I want to read about someone even more hardcore who got lost because he was doing something a whole lot more important than dillying around some cliffs," then I have the perfect book for you. If you'll remember, Aron Rolston is the guy who got trapped under a boulder and had to cut his own arm off just so that he could trek through some desert paths and get to safety. Shit is hardcore, but Rolson has nothing on Jan Baalsrud in We Die Alone by David Howarth. Check out more info here:
Put it this way, Rolston cut off his hand and that shit was undoubtedly gnarly, but Baalsrud cut off nine of his own toes at the top of a mountain while being lashed to a dog sled for six weeks to hide from Nazis scouring the valleys below. Oh, and that's after he fell down a frickin avalanche, which came after he spent days running/swimming away from the Nazis. The truth poignancy comes not just from Baalsrud's suffering, but from the bravery exhibited by countrymen. Anyone who did anything but drag this guy to the nearest Nazi risked the safety of his whole village in helping Jan and yet an astounding number of patriots did just that. Without their help, Jan would have died a lonely man under a pile of snow. Seriously, pick this up if you're itching for some good personal historical fiction.
