Zack Murphy has a target on his back.
When Zach's ex-wife resurfaces after years of silence, he's determined to push her out the door just as she did to him all those years ago, but she refuses to go without issuing a warning: Zach's in danger.
Zach sets out on a hunt for answers and discovers a trail of clues leading back to two dead crime bosses, both from opposite ends of the country.
As he searches for a connection, he's forced to turn to the one woman he never wanted to need again.
