After turning society upside down with her debut story, provincial Charlotte Deveraux arrives in Paris poised for literary stardom. She's not sure where her next rent payment will come from, but she's determined to make a name for herself as a respected writer in the cultural capital of the world.

Antoine de Larminet is the last surviving son of an aristocratic family. In line to inherit a title, he has promised his parents that he'll marry a peer and carry on the centuries-old tradition. He was raised in an antiquated world where love was often found outside of arranged society marriages. Even as the French aristocracy is losing relevance to modernity, Antoine never questioned this commitment to this family legacyuntil his chance meeting with clever and beautiful Charlotte.

Their attraction is immediate, and the more they bump into each other at the clubs and salons of Paris, the stronger their attachment grows. But Antoine can't marry Charlotte because she's as proletarian as they come. And Charlotte will lose all credibility as a writer and social critic if she becomes the mistress of an aristocrat.
