She 

She, subtitled A History of Adventure, is a novel by the English writer H. Rider Haggard, published in book form in 1887 following serialisation in The Graphic magazine between October 1886 and January 1887. She was extraordinarily popular upon its release and has never been out of print. On his twenty-fifth birthday, Leo Vincey opens the silver casket that his father has left to him. It contains a letter recounting the legend of a white sorceress who rules an African tribe and of his father’s quest to find this remote race. To find out for himself if the story is true, Leo and his companions set sail for Zanzibar.
