This is book number 14 in the Parker Novels series.
The hunter becomes prey, as a heist goes sour and Parker finds himself trapped in a shuttered amusement park, besieged by a bevy of local mobsters. There are no exits from Fun Island. Outnumbered and outgunned, Parker can't afford a single miscalculation. He's low on bullets-but, as anyone who's crossed his path knows, that definitely doesn't mean he's defenseless.
