Is The Secret Garden a good book?

The Secret Garden by Frances Hodgson Burnett who meant the book to entertain not to inform or persuade.

It has a few parallel story lines. One of a spoiled, seemingly unloved child of 10 (Mary Lennox) whose parents die and she is forced to move to England into a gloomy sad household with an uncle that doesn't ask for her and staff (mostly) that treat her with disdain. She is forced into a lifestyle and surroundings where she is entirely unfamiliar and ends up discovering beauty, learns to look at herself from a different perspective and helps her cousin to finally thrive.

At the same time it's the story of not being able to move forward and creating a whole reality around a misconception. Young Colin is Mary's cousin because his mother was Mary's aunt (her mother's twin sister). His mother died while she was pregnant with him, causing him to be born prematurely. From that his father went into a depression, and since he (Colin) was weak as a baby, the whole household went on the assumption that he was frail and so he didn't leave his bed for his 10 years of life (thus far). He was treated like he had a terminal disease and he believed he was going to die. they kept him hidden for fear of infecting him.

When Mary found the garden and started to see the life in it and enjoy watching it come to life, she also met her cousin, and made a relationship with him. In doing so, she focused less on her problems and ended up helping him to see that he's as healthy as anyone and he just has to bloom. just like the garden
