C. S. Forester 
African Queen [EPUB ebook] 

A classic tale of love and adventure from the author of the Captain Hornblower series. The film adaptation, which starred Katharine Hepburn and Humphrey Bogart, became one of the most popular films ever made.The African Queen is an old, dirty, ugly, unreliable steamboat – not the kind of boat anyone would take down a dangerous river through the jungles of Central Africa. But Rose Sayer and Charlie Allnut do just that. Why do they do it? The First World War has just begun, and Rose has a crazy plan. She and Charlie set off down the river and come close to death many times, but they survive all dangers – except the danger of falling in love.
