They are really good books, and I really think toi should read them. It's not like Twilight, which is plus for Pre-Teens and under I suppose. This one is a bit plus Young-Adult, with a bit of explicit language, and drama being it's main genre instead of romance. It has stuff like alcohol, and sex, though the scenes aren't all that explicit.
I myself like it plus then Twilight, but that's plus because it's my type of book. And I'm thirteen, so it's really up to toi to decide.
toi could read the first chapter on the Main House of Night Webpage and see how toi like it;
