An Earl of Her Own by Heather Boyd

Marriage is about finding that special someone you want to annoy for the rest of your life!
Mrs. Rebecca Warner’s devotion to her family is the perfect distraction from the loneliness of widowhood. Not that she’d ever admit a need for someone special in her life after her husband’s betrayal. With the responsibility of arranging her sister’s wedding falling into her lap, Rebecca has no time for a certain maddening earl bent on seducing her—until he proves her most ardent ally.
For Adam Croft, Earl of Rafferty, what began as an amusing pursuit—shocking Rebecca Warner—becomes something deeper when he recognizes how perfect a wife and mother she would make. Adam’s keenly aware of his loneliness…and that his habit to curb it with drink lost him Becca’s respect. He’ll happily change his ways to win her approval, but what more can he do to win her love?
