As the new girl in a strange town, Casey is trying desperately to fit in and make friends. When her parents leave town for the weekend, her friend suggests she have a house party. Casey is reluctant to go along, until she realizes maybe this is the answer to fitting in and making friends—and getting back at her parents. They invite a few people and then a few more, using msn and text messaging. Hundreds of people show up and things get out of hand. Casey is in more trouble than she thought possible and now she must decide whether—and how—to do the right thing.
