It's a new school year, and time for a really big change -- "a whole new Stephanie." This year Stephanie plans to be perfect in every way! She's going to wear very, very cool clothes every single day. She'll write only serious things for the school newspaper, and there will definitely be no giggling around boys.

Easy, right? Wrong! Before Stephanie realizes what's happening, she's moved out of her house -- and is caught breaking into the school cafeteria! How did she ever get into this mess?
