Sweet Deceit — Lynn McKay

Diana Rainville would do anything for her aging, beloved spouse. Even the unthinkable: To protect the family legacy, he beseeches her to produce an heir with another man. Diana trembles in her innocence, but agrees to receive Lord Baldwin--for her husband, for a baby of her own. But how can she accept the passion she finds in Gavin Winslow's arms? Nothing more than duty can lie between them. Bound by honor, they part ways. Diana tends her ailing husband; Gavin serves his country. Those tempestuous nights have not only created a child, however--a union has formed. And when disaster strikes, Diana and Gavin prove that the ties binding a man and a woman, ties that promise to last a lifetime, are sanctioned first and foremost by the heart.
