The Heffley family road trip starts off full of promise and then quickly takes several wrong turns, with everything from a fender bender to crazed seagulls. But even the worst road trip can turn into an adventure. Series Information: Let's get one thing straight: Greg Heffley is not keeping a diary. He's not going on and on about his feelings or anything crazy like his mom wants him to do. He's keeping a journal. So that, one day, when he's rich and famous, he can use it to prove that middle school is "the dumbest idea ever invented." Author Jeff Kinney's pitch-perfect tone, incredibly relatable humor, and cartoon illustrations make each of the books in this bestselling series a laugh-out-loud trek through middle-school mayhem.
