When Lady Sophia Winterbourne-Stratford-Forrester assumes she will die imminently of a weak heart, she needs a plan that won’t leave her daughter an orphan. American ambassador Mr. Oliver Mattingly is in England on holiday, but after a few meetings, he falls in love with her. When he hears of her plight, he nobly offers marriage. Weeks go by in congenial, carnal wonder, but when a freak accident occurs that should have stopped Sophia’s heart but doesn’t kill her, they both wonder if they’ve been trapped into a false union. Only they can decide if they want the romance forever.
