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