Tally has finally become Pretty. Now her looks are beyond perfect, her clothes are cool, her boyfriend is totally gorgeous, and she's completely popular. It's everything she's ever wanted.

Now she has to choose between fighting to forget what she knows and fighting for her life...

Tally discovers another brand new world. In Extras, it's all about who you know, and how much you have. It's just like LA. Only Paris and Nicole are way dead...
