The Secret Garden by Frances Hodgson Burnett

This is the story of a girl who is very spoilt by her parents ignoring her and leaving her upbringing to an ayah who did not dare to go against her wishes. After her neglectful parents die in a cholera epidemic, Mary Lennox is sent to Mistlethwaite Manor in England, where she soon learns that the whole world does not revolve around her through her experiences there, especially after meeting her cousin, Colin Craven.
