There's a Bat in Bunk Five — Paula Danziger

Marcy's thrilled when her former teacher, Ms. Finney, asks her to be a junior counselor at a new creative-arts camp. This is Marcy's big chance to have a summer away from her family, at a new place where only Ms. Finney knows that she was once a fat nobody. Marcy's sure it will be a perfect summer.

But camp life is anything but perfect as Marcy copes with noisy, giggling girls, including Bunk Five's problem camper, the bat of the title, and the thrills of her first romance.
