Miss Patricia Mayfair is a wealthy, orphaned Regency bluestocking. While in London for the Season, Miss Mayfair spends more time buying books than ribbons, to the despair of her more conventional friend. Begrudgingly attending a dinner party, Miss Mayfair meets Lord Andrew Aragon, who fancies himself tired of London and the ton and never expects to fall instantly head-over-heels. But Lord Andrew is a notorious gambler, and Miss Mayfair has vowed she will never marry a man who indulges in such a vice. Can the leopard change his spots or the rake his habits?
