Ok so I read this book about 2 years ago i cant remember the name of it. I can however remember that it was written by two authors one was named David. So the plot is this two twin sisters were at a party one night with friends and decided it was gettinga little out of hand with the drinking. So they drive home, on the way they get a flat tire and one goes for help. After awhile her twin in the car decided to go look for her. Only to find her raped and murdered in a park.
