House of Cards Series by Barbara Metzger

Never did Alexander "Ace" Endicott, the Earl of Cards, imagine himself to be thrice-betrothed against his will by the doings of three desperate debutantes. So he escapes London to his property in the country, where he follows through with his deceased father's last wish-to find his long-lost step-sister. His search takes a detour and leads him to Nell, who piques his interest. Now, Ace may have to reconsider his rejection of marriage and see if two mismatched lovers can make a royal pair.

Years ago, Captain Jack Endicott's half-sister vanished after a carriage accident. He now sets out to honor his father's dying wish and find her. Jack plans to open a lavish gaming parlor and hire only beautiful ladies to deal cards, possibly finding his sister. All he needs is a little luck. Instead he finds prim schoolteacher Allie Silver, who needs a guardian for one of her most precocious pupils. With such an unlikely duo, all bets are off in a wild game of romance.

All of London knows the story of the vanished Lady Charlotte Endicott and the handsome reward that will accompany her safe return. Scores of blond-haired, blue-eyed impostors have tried their luck at Jack Endicott's casino claiming to be the girl, only to be turned away-but Queenie Dennis just might be the one. Fate takes a turn when she returns to London posing as a dressmaker fresh from France. Queenie quickly becomes the talk of the town, catching the eye of the handsome Lord Harkness... moreAll of London knows the story of the vanished Lady Charlotte Endicott and the handsome reward that will accompany her safe return.
