Marked (House of Night, Book 1)

Another point worth mentioning is the author's obsession with sex. I know its a young adult book, but honestly, a year ago (when I was sixteen) I didn't focus on sex that much. From the supposed oral sex scene, to Aphrodite rubbing her crotch, and Zoey thinking about boobs all the time, it came across as really forced to me. Yeah, I like a little passion in books, and I like some making out or even just brief sex scenes a la "Breaking Dawn" (can't believe I referenced that; HATE that book). But it just felt like sexy fluff that was put it to entice the exceptionally horny teenager into reading.
*SPOILER*
Note: I started reading the second book, but after she started getting dirty with the teacher or whomever, I stopped. I am never reading this series again.
