The weekend in Mexico sounded like a dream holiday, Four guys, five girls and a gorgeous oceanside mansion all to themselves. Except nothing was going the way they'd planned. There was the girl upstairs who was fighting for her life, the phone lines were dead and the explosion in the garage that could have killed them all. But not even that prepared them for what happened next. Because while they were getting some sun, someone else was getting revenge - and the terror wouldn't stop until the weekend was over.
