My first thought upon starting the book was that the narrative voice of seventeen-year-old Bianca (snarky, foul-mouthed, and sexually active) seemed authentically like a teenager. Then I flipped to the back cover and read "Eighteen-year-old debut author Kody Keplinger". The narrator sounds like a real teenager because the book was written by a teenager. Duh. It was a cute, well-written book; I enjoyed it even though it gave me flashbacks to my own angsty, pimply, nerdy, and... duff-y teenage years. I'm so glad I'm no longer seventeen.
