Beauty And The Beast by Arthur Quiller-Couch

A gentle, moral tale about a kind and selfless young woman who offers to take her father's place as a prisoner in a mysterious, enchanted castle; there she finds a shy, monstrous inhabitant whose gentle manners and hidden suffering reveal a tender humanity, and through patience, compassion, and loyalty she breaks the spell that binds him, transforming both their lives and proving that true beauty lies within.
