Intrepid hero Cork O’Connor faces probably the most harrowing mission of his life when a charter planes carrying his wife, Jo, goes missing within a snowstorm over the Wyoming Rockies. Months following the tragedy, two women show up on Cork’s doorstep with evidence that the pilot of Jo’s airplane was not the person he claimed to become. It may not really be definitive proof, but it’s a ray of light in the darkness. Agreeing to research, Cork moves to Wyoming, where he battles the disturbance of local law enforcement who may be on the take, the open hostility of the Northern Arapaho, who have much to reduce if the simple truth is known, as well as the continuing tries on his life by assassins who shadow his every move. At the center of all danger and deception lies the possibility that Jo’s disappearance had not been the finish of her, that somewhere along the labyrinthine path of his search, probably even in the wide shadow of Heaven’s Keep itself, Cork will find her alive and waiting for him.
