Blyton's books often reference the fantasies of pre-pubescent children. Children are free to play and explore without adult interference, more clearly than in most authors before or since. Adult characters are usually either authority figures (such as policemen, teachers, or parents) or adversaries to be conquered by the children. Children are self-sufficient, spending days away from home. This theme is taken to its extreme in two books: Five Run Away Together and The Secret Island: a group of children run away from unpleasant guardians to live on an island together, making a home and fending for themselves until their parents return. Blyton's books are generally split into three types. One involves ordinary children in extraordinary situations; having adventures, solving crimes, or otherwise finding themselves in unusual circumstances. Examples include the Famous Five and Secret Seven, and the Adventure series. The second and more conventional type is the boarding school story; the plots of these have more emphasis on the day-to-day life at school. This is the world of the midnight feast, the practical joke, and the social interaction of the various types of character. Examples of this type are the Malory Towers stories, the St Clare's series, and the Naughtiest Girl books. The third type is the fantastical. Children are typically transported into a magical world in which they meet fairies, goblins, elves, or other fantasy creatures. Examples of this type are the Wishing-Chair books and the Magic Faraway Tree. Alternatively in many of her short stories, toys are shown to come alive when humans are not around.
