Elizabeth Stride has settled on South Carolina's Hilton Head Island to escape her past. Most of all, she wants to leave behind Martin Kessler – a man who will always own a piece of her soul. But his love is a continuing reminder of what she once was: "The Black Angel," a ruthless and efficient assassin.
A young girl is about to be kidnapped from an exclusive Hilton Head tennis club - a girl who unwittingly holds the key to a planned act of terrorism. By joining forces in her rescue, Elizabeth and Martin will put their fate in each other's hands one last time and decide once and for all whether they must live together or apart. In doing so, they will be drawn into a violent struggle - a secret war of greed and fanaticism - from which there will be no haven.
