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?
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.
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.
Usually Zeke loves Halloween, but this year things just seem to be going wrong--he is having trouble finding a good costume, the costume parade at school is a disaster, and he has to take his little sister trick-or-treating.
