What is the theme from the story Anne of Green Gables?

One of the novel's main themes is that of belonging. Anne's greatest desire is to belong to family and community. We can feel her ache when she cries out, "You don't want me! Nobody ever did want me. I might have known it was all too beautiful to last." Anne's romantic idealism, daydreaming and over-sentimentalizing of natural surroundings often reveal a lonely, isolated girl escaping into a world populated by her own imagination. She befriends the cherry tree in full bloom outside her window in the east gable when it appears she will return to the orphanage. Katie Maurice (her own reflection) and Violetta (the little girl's echo) take the place of playmates when she becomes the servant girl for Mrs. Thomas and her drunken husband — or Mrs. Hammond and her twins three-times over. Anne's preoccupation with being good and trying to please, tempering her opinions if not her theatrics, show a young girl seeking companionship, acceptance and love in the female role models she seeks out, the community that raises her and the Cuthberts who have opened their home to her. As Anne matures and comes into her own as a bright, talented young woman, she becomes markedly quieter and surer of herself, prepared for that bend in the road, assured that it is "a million times nicer to be Anne of Green Gables than Anne of nowhere in particular."
