The treatment of psychic phenomena [in Beyond Another Door] is never heavy-handed but is used as an effective device enabling the author to explore the relationship between the girl and her mother and to bring Daria an awareness of herself. The reader can easily identify with the mature, individualistic protagonist as she probes the complexities of love and friendship.
