He refuses to allow any one else to suffer at the hands of a Deverall man. When he meets his childhood friend, Lady Harriet Cornwall, he is determined to stay away from her, despite the fact she makes his heart sing and his body ignite. When the two are caught in a compromising position, he has no choice but to marry the wild, independent Harry. But will his determination never to have children, and his fears about his famiy line, destroy their chance at love?

A Lady Determined to Unmask the Duke:

No, she longs to be just like her mother, a beacon of culture, literature, and fun. And like her mother, she longs for a large family. When she meets Rob again, she can hardly believe the transformation from mischeivous boy to sardonic and mysterious man. In the breath of a single dance, her heart is lost. From their very first kiss, she knows he is the one for her. But he has a dark secret. Will he push her away as he has done to everyone else? Or will she be able to coax her dark duke back into the light to find love?
