H. Rider Haggard 
Ghost Kings 

Sir Henry Rider Haggard was an English writer of adventure novels set in exotic locations, predominantly Africa, and the creator of the Lost World literary genre. His stories, situated at the lighter end of the scale of Victorian literature, continue to be popular and influential. He was also involved in agricultural reform and improvement in the British Empire. "The Ghost Kings" is an exciting novel with a great emphasis on fantasy elements and the supernatural. Indeed, with the exception of its South African setting and the inclusion of such real-life characters as the Zulu chief Dingaan (brother of Chaka) and councillor Mopo (both of whom also featured prominently in Haggard’s 1892 masterpiece "Nada the Lily"), the tale could almost be a novel of hard fantasy.
