Greg Heffley tells about his summer vacation and his attempts to steer clear of trouble when he returns to middle school and tries to keep his older brother Rodrick from telling everyone about Greg's most humiliating experience of the summer.-"Whatever you do, don't ask Greg Heffley about his summer vacation. As Greg enters the new school year, he's eager to put the events of the past three months behind him ... and one event in particular. Greg knows that his survival in middle school depends on his ability to keep the details of that incident under wraps. Unfortunately for Greg, his older brother Rodrick knows about his secret, and would be happy to spill the beans should Greg step out of line. 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, to keep his secret safe. But secrets have a way of getting out, especially when a diary is involved." -- Provided by publisher.
