Through the Eyes of a Blind Duchess by Patricia Haverton

She was the light that guided him out of his darkness…

Locked away in her family’s estate for more than two decades, Aurelia Blackmore has resigned herself to a life of exile.
Blinded in the same fire that killed her mother when she was young, marriage is not even a thought for her. Until the day her father announces her engagement to a man she has never met.
Donovan Harding, the Duke of Oakhampton, has suffered many losses, with his wife and his fortune sacrificed on the altar of an illness. With no good options left, he must marry again. But his new bride’s secret might be more than he can handle.
Tied together by the strings of his son’s violin, their marriage is a precarious one. When a fire claims her childhood home and a constable brings news of a murder, the strings begin to unravel. A familiar voice, awakening memories of her past, threatens to tear away all that she loves, just as it had the fateful night she lost her vision and her mother.
