#1 New York Times bestselling author Dean Koontz delivers a thrilling novel of suspense and adventure, as the lives of strangers converge around a mystery unfolding high in the Colorado mountains—and the balance of the world begins to tilt….  In the stillness of a golden September afternoon, deep in the wilderness of the Rockies, a solitary craftsman, Grady Adams, and his magnificent Irish wolfhound Merlin step from shadow into light…and into an encounter with enchantment. That night, through the trees, under the moon, a pair of singular animals will watch Grady's isolated home, waiting to make their approach.  A few miles away, Camillia Rivers, a local veterinarian, begins to unravel the threads of a puzzle that will bring all the forces of a government in peril to her door.
