They are really good books, and I really think te should read them. It's not like Twilight, which is più for Pre-Teens and under I suppose. This one is a bit più 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 più then Twilight, but that's più because it's my type of book. And I'm thirteen, so it's really up to te to decide.
te could read the first chapter on the Main House of Night Webpage and see how te like it;
