Start with Into Thin Air. Krakauer was on Everest in May 1996 as a magazine journalist embedded with a commercial expedition, and eight people died on the mountain during the storm he survived. The book is a first-hand account written by a participant who is openly unsure how much he can trust his own memory at altitude, and it is the best-written thing he has done.
The obvious alternative is Into the Wild, which is shorter and more famous through the film. It is a fine book. But Into Thin Air is the better start precisely because it is contested — reading it teaches you to read Krakauer the way he should be read, as a reporter with a stake in the outcome, and that habit improves every book that follows.
Read the rebuttal immediately
The climb, by the Russian-born guide Anatoli Boukreev with G. Weston DeWalt, disputes Krakauer's account directly. The central disagreement concerns Boukreev's decision to descend ahead of his clients without supplemental oxygen; Krakauer questioned it, Boukreev answered that the choice let him return up the mountain and pull three people out of the storm alive. Later editions of both books carry replies to the other. Boukreev died on Annapurna the year after the disaster and never wrote a further response.
We are not going to tell you who was right. Two experienced people on the same mountain, in the same weather, remember and interpret the same hours differently, and that is the actual subject.
Left for Dead adds a third voice: Beck Weathers, the client left for dead near the South Col who walked back into camp with catastrophic frostbite. His book is as much about his marriage and his depression as about the mountain.
The earlier work
Eiger Dreams collects the magazine pieces he wrote before any of this, on climbers and climbing culture, and it is where the voice starts — dry, technical, and fascinated by people who make indefensible choices for coherent reasons.
Into the Wild reconstructs the last two years of Chris McCandless, who walked into the Alaskan interior in 1992 and died there. Krakauer argues against the prevailing local verdict that McCandless was simply a fool, and he inserts a long chapter about his own young climbing recklessness to explain why he cares. Alaskans in particular have been arguing with the book ever since.
The investigations
Under the Banner of Heaven moves from mountains to a double murder committed by two brothers in a Mormon fundamentalist offshoot, and uses it as a door into the history of the church and of violence in its early decades. The Church of Jesus Christ of Latter-day Saints publicly disputed the book's history at length.
Read it beside Massacre at Mountain Meadows, by Ronald W. Walker, Richard Turley and Glen Leonard — an account of the 1857 killings by historians working with church archives. Reading the two together, one from outside the institution and one from within it, is a more honest education than either alone.
Where Men Win Glory is about Pat Tillman, the professional footballer who enlisted after 2001 and was killed by his own side in Afghanistan, and about how that was reported upward. Missoula investigates how a series of sexual assault allegations involving university students were handled by police, prosecutors and the university in one Montana town. It is careful, extensively sourced and hard to read; treat it as journalism about institutions rather than as a legal or clinical resource, and skip it if the subject is not something you want in your evening.
Three Cups of Deceit: How Greg Mortenson, Humanitarian Hero, Lost His Way is a short investigation into the bestselling account of Mortenson's charitable work in Pakistan and Afghanistan. Mortenson disputed elements of it; a Montana attorney general's inquiry followed and ended in a settlement with the charity. It is closer to a long article than a book.
Classic Krakauer gathers magazine pieces from across the career and is the right pick if you want one volume rather than nine.
Three books give you Krakauer: Into Thin Air, The climb and Under the Banner of Heaven. The Krakauer hub carries the wider adventure-writing reading.
