SOLVED. group of friends at a party start messing with a gun, accidental shooting [s]

[Ergent]

i read this book awhile back, and i cant remember the title. really good book. it was told from different perspectives of a group of friends. one night they were at a party. the party ended so a few of them were downstairs messing with a gun, thinking everyone had left. but in one of the upstairs bedrooms, a girl and her bf had spent the night. he was sleeping and she was just walking out the door about to leave when the gun went off and she was shot and killed. the rest of the book was about those friends burying her body and trying to cover it up..but tensions started growing among them as one of them started pondering telling the police as his guilt increased. does anyone have an idea or read something similar?
