A Gilded Duchess. Turn of the Century, #2

Evangeline "Birdie" Horst is everything society expects in a Dollar Princess-beautiful, wealthy, spoiled, and determined to marry a title. But when her family detours through the English Lake District, she meets a mysterious groundskeeper who challenges everything she thought she wanted. Ross barely survived the fire that destroyed Keswick Castle as a boy. As the Duke of Rosthwaite, he's spent a decade rebuilding its gardens stone by stone.
He lives and works on the grounds of Keswick Castle, which he opens to paying visitors during the summer. When a sharp-tongued American heiress mistakes him for hired help, Ross seizes the chance to be seen for who he is, not the coronet he wears. But deception has consequences. And when Birdie discovers the truth, she must choose between the gilded future she planned and the haunted, passionate man she's come to love.
