The Ugly Truth was published by Amulet Books in 2010. Greg and his best friend Rowley Jefferson have a falling-out, and Greg must navigate middle school alone — or attempt to find new friends, which proves far more difficult than he expected. Simultaneously, he faces the “ugly truth” of puberty: his school’s health curriculum, physical changes, and the dawning awareness that childhood is ending.
The novel marks a tonal shift in the series: while still comic, it engages with genuine adolescent anxiety about change, loss of friendship, and the irreversibility of growing up.

Growing Pains
The “ugly truth” of the title is not just puberty — it is the realisation that friendships are fragile and that the social skills Greg lacks are exactly the ones that matter. By temporarily losing Rowley, the series acknowledges that Greg’s manipulative behaviour has consequences. The Greg-Rowley dynamic is the emotional backbone of the entire franchise.
Frequently Asked Questions
Are the Wimpy Kid books appropriate for all ages? The target audience is 8–12 years old. The humour includes mild scatological jokes, social cruelty, and family dysfunction, but nothing graphic. Parents occasionally object to Greg’s poor behaviour, though Kinney has argued that the books show consequences, not endorsements.
