Third-grader Zeke Meeks already has two sisters, so he is bitterly disappointed when his new neighbor proves to be a girl--can Charlie change his mind and prove to him that boys and girls can play together?

All the children in the third grade except Zeke Meeks are playing with the newest fad, Puppet Pals finger puppets--will Zeke give in to the pressure and join them, even though he would much rather play basketball?

Zeke Meeks will be nine soon, but he is not looking forward to a party that his sisters want to take over and nobody but his closest friends want to attend--but the alternative is going to Grace Chang's party on the same day, and she is really scary.

Zeke's school is having a fund-raiser and the student who sell the most cake mix will get four tickets to Thrillsville Amusement Park, but Zeke is not having much luck until his great-grandmother gives him a lesson in salesmanship--and he takes his little sister with him.

As if coming up with a school project at the last minute is not enough trouble, Zeke also has to deal with his cousin Sam--who is just too perfect to be completely believable.
