Mary Lennox is sent to Misselthwaite Manor, on the Yorkshire moors, to live with her uncle after her parents die of cholera. There she discovers her sickly cousin Colin, who is equally obnoxious and imperious. Both love no one because they have never been loved. They are the book’s spiritual secret gardens, needing only the right kind of care to bloom into lovely children.
Mary discovers a beautiful secret garden, hidden behind a locked gate on her uncle’s estate, neglected for the ten years since Colin’s birth and his mother’s death. Together with a local child named Dickon, Mary and Colin transform the garden into a paradise bursting with life and color. Through their newfound mutual love of nature, they nurture each other, until they are brought back to health and happiness.
