H. Rider Haggard 
Nada The Lily 

'Nada the Lily' is a factual novel by writer H. Rider Haggard, first printed in 1892. Set in South Africa, the book's characters are all black South Africans. The novel tells the story of the hero Umslopogaas, the illegal son of the great Zulu King and General Chaka and his son for 'the most beautiful of Zulu women', Nada the Lily. Nada the Lily is unusual for a Victorian novel in that its entire cast of characters is South African and Chaka was a real king of the Zulus but Umslopogaas was discovered by Haggard. It's about Zulu Kings and the Nada in the title is the most beautiful of the Zulu woman and is loved by the son of the great king Chaka. It's got everything, adventure and a sad ending.
