If going with something by Jon Krakauer, I'd recommend Into Thin Air (which is so fascinating and disturbing that I read it in a single go, staying up all night, and then immediately re-started reading it again from the beginning) or Under the Banner of Heaven. I think both are more page-turners than Into the Wild (which is good, too, just not as riveting).
Into Thin Air got me into reading books about high-altitude climbing, and the second best one I've read is Touching the Void by Joe Simpson.
Some other page-turners:
In the Heart of the Sea (Nathaniel Philbrick)
Love Thy Neighbor: A Story of War (Peter Maass)
Columbine (Dave Cullen)
The Devil's Teeth (Susan Casey)
Under a Flaming Sky: The Great Hinckley Firestorm of 1894 (Daniel James Brown)
