A missing woman. Her dead husband. A 600-pound tiger. What do they have in common? To what extent must Harvey go to shatter an inconvenient secret?

Dr. Harvey Nolan, a Nobel prize-winning Columbia Professor, isn’t expecting the FBI at his office after his first blood-soaking brush with them many years ago. In a dark and damp dungeon, a frightened woman wakes up to find herself chained to her bed, her screams echo but unanswered. Agent Katie Moulin, a jaded ex-FBI, grudgingly returns to the ground when things get chaotic with a single divergent event.

Caught in a crossfire between a merciless assassin and the FBI for a crime he did not commit, can Nolan clear his name before it is too late? As New York City becomes a hotbed of crime, Harvey's and Katie's lives must intertwine once again. Forced to battle enemies and allies closing in alike, they find themselves surprised by the extent of cruelty people can go to. Or perhaps, could the cruelty be justifiable?
