The Marks of Cain

Tom Knox, the best-selling author of The Genesis Secret, delivers a spine-tingling novel that “may well be the most controversial thriller since The Da Vinci Code” (Jeff Abbott). When David Martinez inherits an ancient map from his dying grandfather, the map—and the promise of two million dollars—leads David into the Basque heart of the treacherous Pyrenees. There a genetic curse and a frightening secret from the past lurk in the shadows. Soon David and a beautiful stranger are on the run from a vicious and relentless pursuer.
