Kristy's mom is getting married, and Kristy is going to be a bridesmaid! The only trouble is, fourteen kids are coming in town for the wedding. Kristy, Claudia, Mary Anne, Stacey, Dawn, and Mallory think they can handle it, but that's before they spend a week changing diapers, stopping arguments, solving mix-ups, and planning activities. It's the biggest job the BSC has ever had, but they'll work together to make sure Kristy's big day is a success!
