Diary of a Wimpy Kid: Dog Days (Book 4)

Greg Heffley's family are going to have to count their pennies this summer.
That means, no beach holiday and lots of 'family togetherness'. Which doesn't sound like a whole lot of fun. The only good thing Greg has to look forward to is his birthday, but even THAT ends in a disaster.
And when his dad brings home a brand-new addition to the family, Greg is outnumbered. It could be a real dog of a summer . . .
