Lovely Bones

Yes she probably thinks she is trapped in her heaven since she can't get out and go back to earth where she would rather be. No I don't think she sees it as a perfect world because in a perfect world she would be alive with her family and friends and since she can't do that then she doesn't think its a perfect world. And it seams like she is always sad in her heaven, and if it was perfect she wouldn't be sad or miserable all the time.
