Secret for a Nightingale

an alternate cover edition can be found here

As a young girl in India, beautiful, high-spirited Susanna Pleydell first became aware of her special gifts to soothe the sick. She put aside her dream of helping others when she met the dashing and sophisticated Aubrey St. Clare.

But Aubrey was not at all what he seemed. Back home in London, Susanna found that the man she had married had a weakness–for opium and the occult. Even more frightening was his strange association with Dr. Damien Adair, a powerful man with a sinister hold over her husband. . . .

When tragedy struck, it was Damien whom Susanna held responsible. Even as she fulfilled her ambition of becoming a nurse, following Florence Nightingale to the Crimea, it was Damien who haunted her dreams and filled her mind, who held the key to the most sinister secret of all. . . .
