Summary
The story begins with Greg Heffley and Rowley Jefferson at the latter's country club, but within a few weeks, Rowley's dad becomes annoyed with all of Greg's complaints and bans him from the country club. The beach trip that they've planned is also cancelled due to lack of money, so Greg resorts to going to the town pool.

Later, Greg and Rowley have a sleepover together, and watch a horror movie obtained from Greg's older brother, Rodrick. After the movie, Greg and Rowley become scared of a muddy hand that might strangle them, which was in the movie. Unfortunately for Greg, his mom finds out about the movie and starts a reading club in which he is the only participant after two days. The reading program, however, is put to a stop when Mr. Jefferson arrives with a huge $83 bill that Greg and Rowley spent at the country club, and he forces the boys to pay it off.

For Greg's birthday, all of his relatives come over. Unfortunately, his mom confiscates Greg's birthday money to pay off the $83 bill for Rowley's father. Greg also gets a "Ladybug" cell phone but it is far from what he expected. After Greg's birthday, Greg's mother allows Rodrick and Greg to each get a fish for a pet. Greg picks out an angelfish and Rodrick decides on a fish labeled as "aggressive." But a few days later, Greg discovers that Rodrick's fish has eaten his.

The next day is Father's Day, so the Heffleys visit Leisure Towers to spend the day with Greg's grandfather. There, Mr. Heffley tells of how his dog ran away to a butterfly farm. Greg's grandfather reveals that he had actually run the dog over and Greg's father takes off in disgust. He then buys a dog which Susan names "Sweetheart" and shortens to "Sweetie." Even though Greg has wanted a dog for a long time, he quickly becomes annoyed at Sweetie, who drools on his pillow, sleeps on his bed, and won't stop barking.

Later, Mr. and Mrs. Jefferson invite Greg to go to the beach with them, and Greg reluctantly goes along. However, he is not used to how close the Jeffersons are to each other, in ways such as sharing one ice cream cone and playing charades. Greg causes a bit of trouble over the next few days, and gets sent home after he snaps a rubber band at Rowley (who is convinced that Greg "burned him").

Greg's mom gets his dad to take Greg to a baseball game. His father tries to keep it a secret, but Greg overhears his father talking about getting rid of someone, and believes that his father is going to sell him. He calls the police before he realizes that his father was actually talking about giving Sweetie away to Grandma. Despite Greg's father being mad at Greg, they find a common ground through mutual dislike for a newspaper comic strip.

The book ends with Greg realizing that summer is over when he sees a photo album titled "Best Summer Ever!" It is a horrible record of that summer, but Greg writes that the person who had taken the pictures told the story.
