Irish book

Yes, I am trying to remember the title of that novel set in Ireland that I read during high school. My mom bought it somewhere and brought it home and read it and then I also read it and there was some not-so-good stuff in it. Funny how mother brings all these books home and then makes me feel guilty for reading them. If I shouldn't read this stuff, why is she reading it? Why did she bring it home in the first place? It just doesn't make sense.
