looking for a story

I am looking for a story. I don't know the author or even if it was on this sight but what I do remember is that guy goes off to college ( he has no family) meets up with girl (also no family) they go for a truck ride. They end up in an accident and she dies, in all the confusion he is mistaken for a patient that is there for SRS. anyway they turn him into the girl that died in the truck accident. Any help would be appreciated.
