Justin Case: Shells, Smells, and the Horrible Flip-Flops of Doom (Paperback)

In Rachel Vail's "Justin Case: Shells, Smells and the Horrible Flip-Flops of Doom," Justin is going to start fourth grade--but first, he has to survive the summer. He "gets" to go to camp every day on a bus. He "gets" to experience all sorts of new things: Bugs. Mess hall food. Flip-flops (they hurt the space between his toes "and "they're hard to walk in). And (gulp ) swimming.
Justin's little sister, Elizabeth, seems to deal with camp just fine. So do his friends. Justin is trying very hard not to be a worried kid anymore, especially when it comes to making friends at camp, including a new kid who is kind of . . . rough. After all, Justin is going to be in fourth grade. It's time to be brave. Right?
