Elizabeth "Lizzy" Tepper is currently the only girl going to Regis Prep School. She was forced to move in to Regis where her brother Billy went to school, given approval to go to the all boys school by the dean, when their parents died in a car crash going to visit Billy. Now Lizzy is nothing like her brother, she never gets into trouble, and always gets good grades which is part of the reason the dean let her attend Regis. But now that she's living with Billy and all his trouble maker friends, she's bound to get into a little trouble. ....or maybe a lot.
