Caitlin would stay at summer camp forever if she could. Her new best friends in the world, Hannah, Mia, and Libby are there. And at home? Every thing's different: Her dad is worried he might be losing his job; her mom is repainting the whole house and making the kids volunteer at a soup kitchen; and Caitlin is starting sixth grade at a new school, where none of the girls are as fun or friendly as her Cabin 7 BFFs.

She's sure it will help turn her luck around ... but when?
