Dukes Do It Better by Bethany Bennett
Lady Emma Hardwick has been living a lie-one that allowed her to keep her son and give him the loving home she'd never had. But now her journal, the one place she'd indulged in the truth, has been stolen. Whoever has it holds the power to bring the life she's carefully built crumbling to the ground. With her past threatening everything she holds dear, the only person she can trust is the dangerously handsome, tattooed navy captain with whom she dared to spend one carefree night.
Captain Malachi Harlow, Duke of Trenton, would rather throw himself overboard than return to society. But when the Admiralty calls him back home, there is no room for refusal. Crossing paths with the delectable Lady Emma is a welcome distraction that takes a more serious turn when they discover they have a common enemy. Working together could help them both-but will it also bring a temptation neither can resist?
