Diary of a Wimpy Kid: Hard Luck (Book 8)

Things haven't been going all that well for Greg Heffley recently.
For one thing, his best friend Rowley has a GIRLFRIEND, so now Greg is in the market for a new best friend. But after he's spent so long training him to be the perfect best friend, finding a 'new Rowley' won't be easy.
And to top it off, his family (including his feral cousins) are coming to stay. Can Greg improve his luck before it's too late?
