Twilight Saga (1st 3 books - Twilight, New Moon, and Eclipse)
by Stephanie Meyer
I am probably the last person on this site to read the series that includes the books, Twilight, New Moon, and Eclipse, so I'm not going to summarize the plot. Instead I'll just comment on why I liked the idea of adolescents reading this series.
Bella is considerate of her parents and their feelings. She does not want to hurt them by her words or actions. She cares about their physical well-being and feels responsible for their happiness.
Bella does not shirk or complain about her responsibilities - cleaning, cooking, laundry, etc. She is competent and mature.
Bella gets her homework done!
Bella loves to read the classics and finds them relevant for today.
Bella cares about her friends - Edward and Jacob, for sure, but Jacob's friends and family, the Cullens, and her high school friends, too.
Bella is accepting, non-judgemental, and non-prejudicial.
I love that a character adolescents look up to and may try to emulate has all of these admirable qualites.
