Max Freeman's old life ended on a night that will haunt him for ever. The night he killed a twelve year old child in self defence in a Philadelphia shootout. The night he stopped being a cop. Now he lives an existence of solitary confinement on the edge of the Florida Everglades, where he answers to no one but the demons that eat away at his conscience. And then he finds the corpse of a child beside an ancient river, and Freeman's past explodes into the present. He is thrust into the centre of the search for a serial killer, distrusted as an outsider by the longtime residents of the Glades and considered a suspect by the police. Freeman must walk a tightrope of distrust on both sides of the law. When another child goes missing, all eyes turn to Freeman, and the ex cop, driven by his old habits and the memories of that long ago Philadelphia midnight, knows that he has no choice but to hunt down the murderer himself.
