In the latest diary of middle-schooler Greg Heffley, he records his attempts to spend his summer vacation sensibly indoors playing video games and watching television, despite his mother's other ideas.

The Heffley family road trip starts off full of promise, 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, and this is one the Heffleys will not soon forget.

"Greg Heffley is caught in the middle as the two halves of his extended family come together in a sidesplittingly relatable summer story! When the Heffley's agree to spend summer break with both Mom's and Dad's relatives at the same time, they have to figure out how to be in two places at once. With Greg caught in the middle, can the Heffley's pull off the ultimate scheme? Or will their vacation turn into a hilarious hot mess?" -- Publisher's description....
