Good Girls by Laura Ruby

Audrey is what is considered a good girl, she is ranked 4th in her senior class, follows the rules and does not get into trouble. One encounter during the summer before her senior year begins starts a change. Audrey and Luke are both at a party and met up, sharing a kiss. From there an Audrey and Luke meet up at every party but never share a word outside of these meetings. On one of these encounters someone comes in and takes a compromising picture with their cell phone. Before she knows what is going on the picture has been sent around the school and even to her parents. Audrey must confront the embarrassment of the photo as well as the consequences of when a "good girl" does something "bad". She comes to understand that the lines between good and bad are not always as clear as people think.
