Summer vacation with the whole family: Bestselling author Jeff Kinney delivers page after page of reading fun in the 19th installment of the comic novel series. It's summer break. But instead of hanging out with his best friend Rupert, Greg is facing a family vacation on Knitterfels Island this year. The whole family crammed together in a tiny beach house and in sweltering heat. If that isn't the perfect recipe for a huge disaster. Under the surface, tensions are already brewing: besides Grandma's closely guarded meatball recipe, there are more family secrets that Greg had no idea about. Will he manage to uncover them by the end of the vacation? Or will he just boil over the mood in the beach house? Guaranteed to tickle your funny bone: a great reading experience with Greg and numerous cool cartoons by Jeff Kinney. Over 290 million books sold worldwide.
