Query: All-time classic adventure

Simply put, this is a perfect book for boys or young men (my husband and sons adore it). It is the story of an epic adventure that includes bits of science, history, ecology, survivalism, and pure unadulterated manliness (felling trees and fighting sharks and other sea creatures alone make my boys happy).It is also a great book in the way of writing. Heyerdahl is quick with a figure of speech or classical reference, and the book reads like a classic, itself. Definitely read it for the historical reference--the thought that "this really happened!" occurred to us as we were reading, but also read it for its literary merits. It is one of the all-time classic adventures.
