When Mary Lennox, a nine year old orphan, is forced to move to England to live with her Uncle, she is seen as selfish and disagreeable by everyone at Misselthwaite Manor. As she tries to settle in, Mary starts to explore the big, gloomy house on the Moors that will be her new home. In a flower bed, she discovers an old key that leads her to a secret garden, left locked and neglected for ten years.
Mary befriends her maid's brother Dickon and meets her sickly cousin Colin, whose existence had been hidden from her. As the children's friendship grows and the garden is brought back to life, the trio find happiness, mystery and magic beyond their expectations.
Frances Hodgson Burnett's charming children's story was first published in 1911 and became an instant classic.
