For years, Lauren Reay has experienced vivid dreams of a castle keep and a chapel overlooking the sea. Then she finds the real place: a restored 16th-century Blackness Tower on the coast of northern Scotland. Inside the tower, owned by handsome but reclusive Douglas Sutherland, she finds a 19th-century portrait of a 16th-century woman... who has Lauren's face. Blackness Tower holds strange powers and elemental presences that will change Lauren's life forever.
