Lenny and Mel kick off their incredible summer vacation by doing something huge, something they haven't done since last nothing. They loaf. They doze. They dig into the fridge and come up with new and exciting lunch foods. They're bored -- and it's great! Then August hits, and it's time to go to the cabin. This means piling into the car with Grandma and their parents at the crack of dawn, and driving miles away to breathe fresh air, climb trees, and play with sticks. Yuck. Dad says it'll be an "adventure." But Lenny and Mel know this is parent code for "bad stuff." Why can't they just do what they want this summer?
Much like the Wimpy Kid books with typical dry kid humor and lots of silly illustrations, twins Lenny and Mel really want to do nothing, nothing at all, for their summer vacation. That would make for a boring book so of course things happen. Probably for a slightly younger audience than the Wimpy Kids..
