For years, Lauren Reay has experienced vivid dreams of a castle keep and a chapel overlooking the sea - and then she finds the real place: the restored 16th-century Blackness Tower and the ruined 12th-century St. Bride's chapel, on the otherworldly 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, one who has Lauren's face. Blackness Tower holds strange powers and elemental presences that will change Lauren's life forever. Can Ewan Calder, an archaeologist excavating the cemetery at the chapel, help? Psychic-researcher Magnus Anderson might be able to explain everything rationally - but will he even try?
