... girl who takes up a job as a house help for a distant relative just to support her struggling family ...

Until there it could be me (even if I am not working for a relative). But I am lucky that despite of the hard work my employers are altogether nice and their children always liked me ... while the girl in that book has to suffer a lot. And I fear it actually happens quite some times in reality ... Also some of my helper colleagues are struggling because they are treated like slaves (but at least so far I never have heard anything of sexual abuse).

After your description I guessed you would give at least 4 points out of 5, but maybe the ending was not convincing enough and also you are a very critical reader, hehe.
