Allie plans on having the best weekend ever when she finds out Erica's sister Missy is in the regional Twirltacular baton competition-until Allie's mom announces that she has to go to Brittany Hauser's birthday party instead. But Allie doesn't even like Brittany Hauser, nor does she want to go to a party with Brittany and all her snobby friends...

But when Allie finds out Brittany's party includes taking a stretch limo to Glitterati, the store of the girls' dreams, and spending the night at a deluxe hotel suite, she decides maybe Brittany's not so bad after all.

Allie doesn't want to miss Missy's grand performance at the Twirltacular. But she's always wanted to ride in a limo! How can she explain to her best friend that she's decided to go to Brittany's party instead? Will her little white lie blow up in her face? And when everything about Brittany's party goes wrong, will she break all the rules to do what she knows is right?
