Frances Hodgson Burnett's The Secret Garden

When orphan Mary Lennox arrives from India to live with her uncle, everyone at Misselthwaite Manor thinks her a most disagreeable child. Then one day she discovers a secret garden, locked and hidden for ten years. With the help of Dickon and her spoilt, invalid cousin, Colin, Mary brings the garden back to life; and as she does, the mystery behind it is revealed. An instant classic, The Secret Garden has been cherished by generations of readers since its publication in 1911.
