British writer Frances Hodgson Burnett is the author of Children's novels in which she focuses on the growth of children in the social circumstances of life at the turn from 19th to 20th century. This thesis analyses the selected author's novels: The Secret Garden, Little lord Fauntleroy and A Little princess in order to determine their suitability for contemporary readers, primarily children. Additionally, the similarities and differences of literary works and film adaptations of the same name are compared. The author presents difficult topics, that are still relevant till this day in the world, through the destinies of her main characters. And with the help of these books, everyone can easily approach pupils and children in general, and start a conversation about these topics, which may end with good deeds and helping those in need, following the example of Mary Lennox, Cedric Errol and Sarah Crewe.

Moreover, in this thesis, the similarities, and differences of the novel The Secret Garden and the movie adaptations of the same name were compared, as well as the movie adaptations to each other.
