Dog Days (Diary of a Wimpy Kid #4) (hardback)

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?
