Evangeline Levison has never quite fit the mold of a traditional English lady. Orphaned at ten years old, the New York heiress was brought across the Atlantic to be raised by her loving Aunt Cora and her doting Uncle Robert, the Earl of Grantham. Growing up at Downton Abbey, Eva found a sister and partner-in-crime in the rebellious Lady Sybil, while her modern American sensibilities and favored status in Robert's eyes earned her the frosty resentment of cousins Mary and Edith. By the spring of 1912, the sinking of the Titanic throws the estate's future into chaos, but nineteen-year-old Eva is more concerned with the changing world than finding a husband. That is, until Lord Alistair Stirling, the powerful and traditional Marquess of Keith, arrives at Downton. While Mary Crawley deploys her finest charms to capture the season's most eligible bachelor, Alistair finds himself entirely undone by Eva. Having known her since childhood, Robert is fiercely protective of his orphaned niece, but he can't stop the immediate, electric spark that forms when Eva openly challenges the stuffy young Marquess across the dinner table. Spanning all six seasons of the beloved series, The American Marquess follows Eva and Alistair from the rigid drawing rooms of the Edwardian era through the devastating trenches of the Great War and into the roaring twenties. Together, they must navigate family duty, intense societal pressure, and the grief of a changing world to prove that a modern love can conquer the oldest traditions.
