H. Rider Haggard 
Yellow God: an Idol of Africa [EPUB ebook] 

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 Yellow God: An Idol of Africa", originally published in 1908, is another of Haggard’s African novels, and it features many elements of the fantastic, such as a magic mask and fetish objects, a lost race, reincarnation, and an immortal woman whose many husbands she has preserved as mummies!
