My Last Duchess by Daisy Goodwin

Cora Cash, possibly the wealthiest heiress in 1890s America, has been raised to believe that money will open every door to her. But when her mother whisks Cora to England to secure her an aristocratic match, Cora is dismayed by the welcome she at first receives. The great English houses in which she is entertained are frosty and forbidding, dogged by intrigue above stairs, and gossip below. And it is only when she loses her heart - to a man she barely knows - that Cora realises the game she is playing is one she does not full understand, and that her own future happiness could be the prize.
