When Catriona Drouot, a young music therapist, honours an opera diva's dying request to help her son, Umberto Monteverdi, recover his musical gift, she knows it will be a difficult assignment. She had shared a night of passion with the once-celebrated composer ten years before, with unexpected consequences. The extent of her challenge becomes apparent when she arrives at her client's estate on the glittering shores of Lake Como, Italy. Robbed of his sight by a near fatal car accident, the man is arrogant, embittered and resistant to her every effort to help him. Still, Catriona sings a siren's call within him that he cannot ignore. Caught up in the tempestuous intrigues at Umberto's Palladian mansion, Catriona discovers that her attraction to the blind musician is as powerful as ever. Soon she realizes that hers is not the only secret that is rippling uneasily below the surface. Dark forces haunt the sightless composer, threatening his life - for the second time. Concerto is a sensual and romantic story of lost love and forgiveness, destiny and difficult choices, and of a heroine determined to put things right at last.
