House of Anubis follows Nina Martin, an American girl who moves to England and begins school at a boarding house called...you guessed it, House of Anubis. Nina soon finds the house to be haunted after one of her classmates, Joy, has mysteriously vanished. Joy’s best friend, Patricia, suspects Nina has something to do with Joy’s disappearance. As a new resident and as an initiation to the boarding school, Nina is forced to spend a night in the attic where she realizes that this mysterious house has a hidden secret. Along with the help of a senior citizen named Sarah who had lived in the house years before, Nina and some of her fellow classmates form a secret group called “Sibuna” and search for the mysteries and treasures hidden in the House of Anubis, all while faced with normal teenage issues such as growing up, love, pranks, and friendship.
