The Kon-tiki expedition: by raft across the South Seas, by Thor Heyerdahl.

This book is about a man who sailed across the ocean from South America to here, the South Pacific, on a raft. He and 5 others made the journey to prove that Maori and other Pacific peoples may have travelled from South America long ago, when they only had balsa-wood rafts (stone-age).

It's an amazing adventure, travelling this close to nature, their boat gains pilot fish just like a shark's, flying fish land on their deck every morning which they fry for breakfast, when they are bored they pull sharks backwards out of the water by their sandpapery tails. It's one of those really amazing one-with-nature experiences.
