Can she save me?

Katie Ryan isn't completely your typical 17 year old. She has a junkie for a mom named Lucy and a dad she's never met. She's home probably 2 nights a week, other nights she crashes where she can to get away from her mom and the bastards she brings home. Katie smokes, drinks, steals, starves and cuts to try and cope with her past and depression. She's into girls has been for as long as she can remember. She's still in school, goes occasionally just to make sure her grades are good enough for her to pass. But then the new girl comes, will Katie end up changing for the better or getting her heart broken and go completely down hill once the new girl finds out about her past? Can this new girl change Katie?
