Heart of Darkness
Heart of Darkness (1899) is a novella by Polish-English novelist Joseph Conrad about a narrated voyage up the Congo River into the Congo Free State in the so-called "heart of Africa". Charles Marlow, the narrator, tells his story to friends aboard a boat anchored on the River Thames. This setting provides the frame for Marlow's story of his obsession with the ivory trader Kurtz, which enables Conrad to create a parallel between what Conrad calls "the greatest town on earth", London, and Africa as places of darkness.
Queen of Hearts (Alice's Adventures in Wonderland)
In the manga "Alice in the Country of Hearts", the Queen of Hearts is known as Vivaldi. She isn't as much a main character, though, and she has very few parts in the current books. Vivaldi rules Heart Castle and is feuding with the other territories over Wonderland. She is beautiful with black hair, unlike other adaptations. She speaks in the majestic plural, I.E, "We are happy you are here to see us." As discovered through Heart no Kuni no Alice the game by Quinrose (the predecessor to the manga) Blood Dupree (The Hatter) is Vivaldi's little brother though it is alluded to be a romantic interest for Vivaldi until Alice discovers the secret.
