Lost Horizon

Origin
James Hilton's Lost Horizon is the origin of Shangri-La, a fictional utopian lamasery high in the mountains of Tibet. The narrator reads a manuscript written by Rutherford telling the story of four travelers’ experiences, after being hijacked, in a mysterious valley known as Shangri-La. Conway, the main character of the four, falls in love with the Valley of Blue Moon and eventually is named the new High Lama. Barnard and Miss Brinklow also find happiness in staying there. Only Mallinson desperately wants to leave and his negativity creates an imbalance there for all the characters. Conway agrees to backtrack out of the valley however everyone else in the party dies along the way. Distressed Conway's last detail in his manuscript was that he was leaving to return to the paradise he had loved and lost. In the end the narrator and Rutherford lament Conway's last desperate act hoping that Conway found Shangri-La again.
