After witnessing how love embittered his uncle and broke his father, Felix Havers, Earl of Ware vows never to love. He conceals his emotions behind a wall of wit and charm, and is celebrated as the master of entertainments—parties, picnics, races. When his best friend's wallflower sister needs to find a husband, he promises to make her the toast of London... without losing his heart.

Miss Sarah Colton has given up on the pursuit of marriage. When her parents learn she intends to open a millinery shop, they give her an ultimatum: choose a husband or they'll do it for her. She accepts Felix's help, never imagining their scheme will ignite a mutual attraction neither of them dare indulge. But when tragedy strikes, can they heal each other or will the demons of Felix's past consume them both?
