What Kind of Girl by Alyssa Sheinmel

The girls at North Bay Academy are taking sides. It all started when Mike Parker's girlfriend showed up with a bruise on her face. Or, more specifically, when she walked into the principal's office and said Mike hit her. But her classmates have questions. Why did she go to the principal and not the police? Why did she stay so long if Mike was hurting her? Obviously, if it's true, Mike should be expelled. But is it true?

Some girls want to rally for his expulsion—and some want to rally around Mike. The only thing that the entire student body can agree on? Someone is lying. And the truth has to come out.
