The DUFF (Designated Ugly Fat Friend)

The DUFF follows Bianca Piper, a high school senior who is shocked to learn she's considered the 'Designated Ugly Fat Friend' among her more popular friends. Insulted but also recognizing some truth, Bianca decides to shake up her social standing. She forms an unlikely alliance with Wesley Rush, a charming jock, agreeing to help him pass science if he helps her become more socially desirable. Their arrangement leads to unexpected feelings, challenges Bianca's self-perception, and forces her to confront bullying and superficiality. The book addresses themes of identity, self-acceptance, friendship, and family issues, including parental conflict. While the publisher description mentions Bianca 'starts sleeping with' Wesley, the narrative focuses more on their emotional connection and the social dynamics of high school.

Seventeen-year-old Bianca Piper starts sleeping with Wesley Rush, a notorious womanizer who disgusts her, in order to distract her from her personal problems, and to her surprise, the two of them find they have a lot in common and are able to help each other find more productive ways to deal with their difficulties.
