H. Rider Haggard 
Dawn 

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. Haggard later said he was inspired to write the book while living in Norwood. He and his wife were attending a Church service when they saw sitting near them "a singularly beautiful and pure-faced young lady". (Excerpt from Wikipedia)
