Mmkay I read this one book a while back and I don't know where the heck it went. Its a Luke Hemmings 
fan fic and I thought it was called black ice but I guess not...so in the book Luke runs this chick over and totally fudges up her leg and he's a total butt about it and the chick is depressed because her old best friend r worded
 her and then like slit her wrists
IF THIS RINGS A BELL 
 TELL ME WHAT IT IS.
