Mary Lennox was a bad-tempered, selfish girl. At the age of nine, her parents died during an epidemic and she was taken to live with her uncle, Mr. Archibald Craven, in Yorkshire, England.

In the beginning, she hated everything about Yorkshire, but with the care and friendliness of the people and animals there, she began to reach out to everyone. However, she found that there seemed to be some sorrowful secrets about her uncle's house.

First, there was a secret, desolate garden in which her aunt died. Then there was a sick, bedridden boy in the house who turned out to be her cousin. However, with her care and dedication, Mary transformed the secret garden and even her cousin's health. Finally, when Mr. Craven came home from a long trip in Europe, he found one more secret about the house. But the secret, this time, was an exceptionally cheerful one.
