Georgette Heyer was so good at writing romances that she created an entire of genre of imitators, the Regency romance market. Her books are light, witty, and well-educated. They are extremely well-researched, and laced with literary references (I now must read Marmion), Cotillion is one of my favorite of her works. I love Freddy, the hero, as the antithesis of both the hero and the anti-hero. He is not brooding, dark, and sullen - or strong, manly, and serious. He is frivolous, fashionable, and addicted to comforts. Very refreshing.
