Each Passing Hour Brings Them Closer to a Deadly Showdown

Just as FBI Special Agent Addison Leigh reaches the pinnacle of her cybercrimes investigation into a firearms-smuggling ring, she's attacked and left in a coma with no memory of the incident--or of her estranged husband who rushes to her bedside.

Deputy U.S. Marshal Mack Jordan may have let his past military trauma ruin their brief marriage, but Addison never gave up on their relationship, and he promises to hunt down the man who attacked her. Mack failed her once when he bailed on their marriage, so he's not about to let her down again, especially after a second attempt on her life is made. Soon it becomes clear that something very sinister is going on, and the killer won't rest until Addison is gone for good.
