The urge within him is overwhelming, and Kerovan - he of the cloven hooves and amber eyes - is driven toward the mountains - toward the dark. With him goes the Lady Joisan, who carries with her secrets unknown to Kerovan. By calling upon the powers within themselves, willing the forces of light to fight against the forces of the dark, they reach their destination...only to face That Which Runs the Ridges in the final battle. Everlasting undeath - and horror for all the world - will take them if they fail.
