Herman Melville 
Typee 

Based on Melville's actual experiences after having jumped ship in the Marquesas Islands, this work was extremely popular, and provoked disbelief among its readers until the events it described were corroborated by Melville's fellow castaway, Richard Greene. While the book is based on fact, Typee is properly considered a work of fiction: the three week stay on which the author based his story is extended to four months, and Melville drew extensively on contemporary accounts by Pacific explorers to add cultural detail to what might otherwise have been a straightforward story of escape, capture and re-escape.
