Kinney's "New York Times"-bestselling Wimpy Kid series returns with Book 4, which finds the sarcastic and sharp-witted ("Toronto Globe and Mail") Greg on summer vacation with his family.

It's summer vacation, the weather's great, and all the kids are having fun outside. So where's Greg Heffley? Inside his house, playing video games with the shades drawn.

Greg, a self-confessed "indoor person," is living out his ultimate summer fantasy: no responsibilities and no rules. But Greg's mom has a different vision for an ideal summer . . . one packed with outdoor activities and "family togetherness."

Whose vision will win out? Or will a new addition to the Heffley family change everything?
