Unseen

And why did she abandon her children?

Thomas Kent is determined to find out. Asked to pick up a "package" at the airport by an old friend he barely remembers, Thomas is shocked when he finds two desperate children looking to him for help. As he's reluctantly drawn into the murderous plot of a ruthless cult, Thomas is forced to come face-to-face with his own torturous guilt over the tragic loss of his family and faith. Why does the cult so desperately want the kids? Their mother, Justine Bishop, holds the key. He just has to find her . . . or die trying.
