MY SPOILER FREE THOUGHTS: I loved/enjoyed this book, despite the fact that I started reading it because of the film trailer —which the film seems to have taken a different angle on the story. Bianca was a great character despite some of her flaws. I didn't like how she treated her friends from time to time, though it was understandable. Great book! You must read it, now! It's around 280 pages.— The DUFF is about this girl named Bianca who is dealing with all this life stress. Among this she runs into a guy she hates for many reasons one of the reasons is he, who basically insults her by calling her the D.U.F.F the designated ugly fat friend. She later learns all these things about her family, and ex-boy friend, and cannot deal with it anymore until one day she kisses Wesley, and finds a way to relieve all her stress.
