Black ice

January in Gotland. The days are short, the air is cold, and all the roads are covered in snow. On a deserted, icy backroad, these wintery conditions will soon bring together a group of strangers with a force devastating enough to change their lives forever when, in the midst of a brief period, a deadly accident and two separate crimes leave victims in their wake. Four years later a single phone call is all it takes to bring back the terror of that day and to set in motion a plot for revenge.
