Las reglas de Rodrick es la divertidísima segunda parte del Diario del Wimpy Kid, un auténtico fenómeno mundial. Mejor no preguntarle a Greg Heffley qué tal la pasó durante las vacaciones de verano, porque no quiere ni oír hablar del asunto. De hecho, al empezar el nuevo curso Greg está deseando olvidar los últimos tres meses de su vida, en particular cierto acontecimiento… Por desgracia para él, su hermano mayor, Rodrick, lo sabe todo sobre ese incidente que él querría enterrar para siempre. Y es que todos los secretos acaban saliendo a la luz… sobre todo cuando hay un diario de por medio. ENGLISH DESCRIPTION Secrets have a way of getting out, especially when a diary is involved. Whatever you do, don't ask Greg Heffley how he spent his summer vacation, because he definitely doesn't want to talk about it. As Greg enters the new school year, he's eager to put the past three months behind him . . . and one event in particular. Unfortunately for Greg, his older brother, Rodrick, knows all about the incident Greg wants to keep under wraps. But secrets have a way of getting out . . . especially when a diary is involved. Diary of a Wimpy Kid: Rodrick Rules chronicles Greg's attempts to navigate the hazards of middle school, impress the girls, steer clear of the school talent show, and most important, keep his secret safe.
