The Lyon and the Lamb by Elizabeth Keysian

He’s dashed all her hopes. She won’t ask him for help again…
Only the production of an heir can save Lady Araminta Lamb. The problem is that she’s a childless widow who, after an abusive marriage, can’t bear the thought of a man’s touch. But when her desperate attempt to adopt a child is foiled by the powerful Leo Chetwynd, Earl of Aylsham, there’s only one option left to keep her home and her fragile sister safe. She must gamble everything on Mrs. Dove-Lyon’s outrageous matchmaking scheme.

Playing by Society’s rules hasn’t done him any favors. Perhaps it’s time to break those rules…
Leo Chetwynd needs money urgently or his precious orphans will be cast out. A disastrous business venture has cost him all his capital, and there’s nothing left to offer but himself. Marriage to an heiress is the only solution that he and his scapegrace brother can think of, but first, he must go to the Lyon’s Den and prove his skills as a lover. If Leo accepts Mrs. Dove-Lyon’s choice of heiress, sight unseen, the orphanage and the family name will be saved. He can only pray that the chosen heiress isn’t the anonymous veiled widow who has become his enemy.
She’s the last woman on earth he could ever marry…
