A must-read for anyone who likes YA. The DUFF is a fascinating view of high school dynamics, not just between guys and girls romantically or simple classroom rivals but also of friends. You get Bianca's pov, and when she discovers what DUFF means, although she's insulted (because it's horrible), she feels like it fits her. And then you find out her friends feel like it fits THEM. That's because everyone DOES feel like a DUFF sometimes. Or all the time. Insecurity is something that can plague you at any age, but I remember how vulnerable I felt to insecurity when I was in high school. 
 Watching Bianca and Wes's relationship is also quite fascinating. They have great chemistry and amazing tension on all sides. I completely understand how, despite the fact that Wes is a douche, he makes Bianca feel safe because he knows the worst parts of her and she feels like she has nothing to lose. I love how honest Bianca and Wes are with each other. They definitely keep some things private, especially regarding their family situations, but they don't put on a veneer when they're alone. They're free to be open without repercussions and consequences that can come from being honest in high school. 
 I'd be remiss if I didn't mention that The DUFF is fantastic for being sex positive. This goes back to how honest Bianca and Wes are with one another and how that translates to feeling safe together. Bianca is never made to feel like she's a slut or trampy because she wants physical intimacy, and I appreciate that for all his jerk moments, Wes in particular never shames her (because if he did, he would be a hypocritical prick). 
 A++ definitely a must read.
