Allie Finkle's starting her first day of school at Pine Heights Elementary! Plus, she's getting a new kitten, the first pick of show cat Lady Serena Archibald's litter!

But being the New Girl is turning out to be scary, too, especially since one of the girls in Allie's new class — Rosemary — doesn't like her. In fact, Rosemary says she's going to beat Allie up after school.

Everyone seems to have an opinion on how Allie should handle the situation. How can Allie tell who's right? Who knew it was going to be so hard being the New Girl?
