H. Rider Haggard 
Elissa 

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. Classic Rider Haggard with all the usual ingredients: lost city, adventuring hero, beautiful priestess, invading armies, love, betrayal, and self-sacrifice. Glorious fun. (Excerpt from Goodreads)
