The Spraggs, a wealthy family of Midwesterners, are visiting New York City to marry off their beautiful daughter Undine. While Undine’s beauty catches the attention of several high-society men, she finds it difficult to fit in with the old-money social circles that rule New York. When she finally marries Ralph Marvell, she embraces a life full of frivolities, which eventually leads to her tumultuous demise. Best known for inspiring the hit series Downton Abbey, this classic novel is a scathing critique of ambition featuring one of the most ruthless heroines in literature.
