As a Special Operations soldier, Dane Cooper was trained and tested to handle the toughest, most dangerous situations around the world. He was not, however, prepared for the abduction of his daughter.

That kidnapping sends him into a downward spiral, the depths of which are unknown even to Dane. But a lifeline is thrown to him by a mysterious cabal, which sees his skills as paramount to helping others.

Now investigating other grieving parents' cases, Dane must conceal his efforts from the zeal of an FBI agent hot on the trail of the vigilante cabal, a dedicated Virginia Bureau of Investigation team, and an elusive network of monsters at the center of it all. Punishing the wicked while searching for his little angel, Dane must also overcome the struggle with his own demons.
