Sanity (A Gotham High Story)
I kinda suck at descriptions but here goes.
Harleen Quinzel is new to Gotham City, a town known for its high levels of crime. Her single mother couldn't afford to send her to a nice private school, so smart, sweet Harleen is forced to attend Gotham High, the school that all of Gotham's juvenile delinquents are enrolled at. How will Harleen survive her new life in Gotham? With the help of new friends, and possibly the baddest kid in school.
