When Polyanna Whittier goes to live with her sour-tempered aunt after her father's death, things seem bad enough, but then a dreadful accident ensues. However, Pollyanna's sunny nature and good humour prove to have an astonishing effect on all around her, and this wonderful tale of how cheerfulness can conquer adversity has remained one of the world's most popular children's books since its first publication in 1913.
