The problem with killing her enemies, Navy Trent learns, is there's no one left to fight. So when Byron Macalester asks Navy to go undercover to save his daughter, Navy says yes. Because she owes him. Because the story of a woman falling in love with the wrong man echoes her past. Because the men she killed a year ago have never left her. She'll go even though it may cost her the one worthy thing to come into her life in the past year, her relationship with Jackson. In Hackerville, Byron will discover the man he thought was a monster is just a victim. Jackson will discover the woman he loves might actually love him back. And Navy will discover survival is about more than knowing how to kill.
