In the midst of the lowest season of his life, archaeologist and professor Jacob Stone gets drawn into the adventure of his life. Along with his grown children, R.A. and Ryder, Jacob uncovers a secret family legacy that reaches back to the days when Jesus walked the earth. At the same time, a shadowy enemy is in pursuit of ancient secrets and treasures held by an equally mysterious group called The Guardians. Across the millennia, whispers have spread about a map...a map made by the first human being born on earth...a map that leads to the first home of mankind...a map made after a return to the Garden of Eden. If the stories are true, the map maker also managed to retrieve the most sought out treasure of all. Are those legends true? As Jacob is confronted by the secrets of his family's past, the enemy draws closer and closer to the most elusive treasure trove of history; the treasure of the Knights Templar. This enemy must be stopped at all costs...but what will that cost be and will Jacob embrace the legacy of the Stone family as the past, present, and future all collide at the same point in time? From the bayous of south Louisiana to the mountains of France, CRYPTEX: THE MARK OF CAIN follows a journey of healing, faith, and family as good and evil come face to face and clash over the treasures of the past in pursuit of an eternal future.
