I’m not much of a reader . . . but when I do . . . I really liked “Into Thin Air” (true story of Mt Everest expedition gone bad – I think a movie based on it coming this fall) and the Vince Flynn (gov’t/spy) novels are great!
I’m also a Jon Krakauer fan. Other books besides “Into Thin Air” are “Under the Banner of Heaven” (scary violent faith account of the FLDS) & “Where Men Win Glory” (Pat Tillman story).
I also liked Joe Simpson’s Book “Into the Void” (mountain climbing in the Andes gone bad).
Or… “The Indifferent Stars Above” by Daniel James Brown (Donner Party account).
