If you have read the book "Starnger with my face" by Lois Duncan then you can read this. This is how I would have ended the story! please read!

Try And Piece It Together ! :

A group of teens go out to a cabin for a little weekend get away when three unexpected strangers come to crash their party. Will they make it to sunrise? Or will they be dead before dawn?

Set after the film The Strangers starring Liv Tyler and Scott Speedman, this is about Shelley, who on her 18nth birthday is attacked by masked assailants, who maybe aren't all strangers to her after all...
