The Garden Warrior

It is the early 1930s, and a little girl named Diane and her older brother, Christopher, are sent away to live at their grandmother's house for a week. But what Diane does not know is that the secret garden, that is forbidden, is magical. The garden always speaks to her, but Christopher does not believe that is true. Will Diane be able to convince her brother, find out her grandmother's darkest secret, and possibly prove that she is the garden warrior she is supposed to become?
