Marianela is a novel written by a Spanish author Benito Pérez Galdós in 1878. It is a tragic but lovely story about a poor orphan girl whose name was Marianela, but almost all people called her "La Nela." Marianela lives with the foreman's family of a rich state where mining is the main industry there. The girl frequently sings to Pablo, a blind boy who believes she is beautiful because of her voice. Pablo hopes his sight can be restored and promises La Nela that he will marry her after the operation if it is successful. Yet, fate writes another scenario.
