Shattered

It starts as a kid''s game to while away the long drive across country. It ends in a grotesque nightmare of death and destruction.
Alex and Colin are travelling three thousand miles by car to a golden city and a golden girl. She''s Colin''s adored sister, Alex''s ravishing new wife. But she could cost them their lives.
Someone''s out to get them. To destroy their dreams. To plunge them into a paranoid world where every sound could be the last thing they ever hear.
