The Indomitable Miss Lacey

Miss Madeline Lacey-world traveler and spinster-is a far cry from the other young ladies making their debut in London society. But instead of wilting into an aging wallflower, she surprises everyone by attracting the attention of a wealthy country gentleman and a newly made rough-around-the-edges earl. Except one lacks an adventurous spirit and the other is allegedly betrothed to the daughter of a marquess.
And then there is the problem of what to do with the many artifacts Miss Lacey's father accumulated during eighteen years of exploration, as well as the deep, dark secret that Miss Lacey is not as penniless as society assumes. Disaster looms as sheer stubbornness on the part of both hero and heroine threatens the possibility of Happily Ever After.
