Where is this? In the book "cut"

In the book "Cut" it takes place at a place called Sea Pines, a big therapy house. But people there call it sick minds. I don't think that Sea pines is a real place, but there probably is somewhere called this, but not the exact thing/propose. Then again though, the author might have gotten the name from a place she went too when she was a kid or a friend went to. Mostly because she can describe the place well. Describing is a very good way to show readers rather than telling, as my English teacher has told me. But it is also easier to describe things when you have an example or connection with the idea.
