"Diary of a Wimpy Kid: Dog Days" is the fourth installment in the highly successful and humorous "Diary of a Wimpy Kid" series, written by Jeff Kinney. This richly illustrated and award-winning book is perfect for both boys and girls ages 8 and up, as well as for readers who normally don't enjoy reading. It's an absolute must-read for the millions of loyal fans of the series. "Dog Days," which has also become a box office hit, tells the story of Greg's summer vacation, a time when he prefers to stay inside with the curtains drawn, watching TV and playing video games. Unfortunately, his mother has other plans that revolve around "family activities," which doesn't sound very appealing to Greg.
