The Blue Edge of Midnight (Max Freeman, #1)

Max Freeman's old life ended on a 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 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. And 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.
