Have you all read The Duff by Kody Keplinger?
If not, and you like a very very well-written YA-novel with problems, issues and sex ..read it. I read it in one night when I couldn't sleep. It was my saviour. I loved it.
I really recognized myself in it. The self-sabotaging streak we all have, at least I did, I didn't use the same method, but I could relate. But most of all I got sucked into the story by the wonderful writing.
