Vinh Murphy--ex-Marine and onetime operative for the elite security firm Troubleshooters Incorporated--has been MIA ever since his wife was caught in a crossfire and killed during what should have been a routine bodyguard assignment. Overcome with grief, Murphy blames the neo-Nazi group known as the Freedom Network for her death. Then he learns of the murder of a Freedom Network leader and comes to believe that the militant group has targeted him--and former police officer Hannah Whitfield--to avenge their leader's death to violence. Now Murphy must face the terrifying prospect of losing another woman he loves.
