Deceptive Heart — Maureen Kurr

He came to her in the darkness of midnight, a stranger hired to perform an outrageous act: Before the night was through, he must sire a child upon the virginal widow of the wealthy Earl of Highcrest. Caught in a tangled skein of love and deception, beautiful young Anne had agreed to the scheme that would give her late husband a false heir, but never did she imagine the throbbing ecstasy she would share with her mysterious lover. During the tumultuous hours before dawn, he would master her senses, bringing her to a fever-pitch of desire that would burn through the lies between them and brand her heart his forever.
