Deep ShadowPaperback, 22 February 2011

In a remote Florida lake, a cave collapses, trapping Doc Ford and two of his friends. Ford manages to escape and surfaces to find help-but two ex-cons are waiting for him. They're intent on diving to the bottom of the deep lake and finding the remains of a legendary plane, supposedly loaded with gold. Ford's expertise is just what they need. And if he doesn't help, Ford and his friends are dead in the water.
