Help

. I went through every single book I own recently, and I seem to be missing one of my favorites. The problem is, I don't remember the name or the author, I haven't read it in so long >.<. All I have is a plot..
The gist of it is...
Two friends are in a car accident, caused by the main character because he was drunk. The bulk of the story is a mystery person murdering everyone involved in the accident, "One by fire, one by water, one by earth", who at the end we find out is the friend's older brother.
I remember the name being something like... Night.. but not Night? I dunno. If anyone knows what I'm talking about, assistance would be -Much- appreciated ^.~.
