Greg nunca cambiará, pero sus padres creen que pueden educarlo. Su padre quiere enviarlo a un campamento de verano para que se convierta en un "hombre de verdad". Con problemas en la escuela y con las chicas, Greg necesita encontrar una solución.
Get ready for a whole new look into Jeff Kinney's Diary of a Wimpy Kid! Introducing the newest Wimpy Kid author--Rowley Jefferson! Rowley's best friend Greg Heffley has been chronicling his middle-school years in thirteen Diary of a Wimpy Kid journals . . . and counting. But it's finally time for readers to hear directly from Rowley in a journal of his own. In Diary of an Awesome Friendly Kid, Rowley writes about his experiences and agrees to play the role of biographer for Greg along the way. (After all, one day Greg will be rich and famous, and everyone will want to know his life's story.) But Rowley is a poor choice for the job, and his "biography" of Greg is a hilarious mess. Diary of an Awesome Friendly Kid: Rowley Jefferson's Journal offers readers a new way to look at the Wimpy world--one fans won't want to miss!
Ve škole se rozmáhá šikana a Greg je jedním z jejích terčů. Rozhodne se řešit problém vědecky, jenže když se jeho poznámky dostanou do nesprávných rukou, jde mu najednou po krku ne jeden, ale všichni školní tyrani do jednoho. Ještě že Gregův kamarád Rowley chodí na karate! Je ale dost možné, že ani to nebude stačit a Greg se bude muset rozhodnout: bojovat, nebo radši vzít nohy na ramena?
