Very few authors can say, with confidence, that they developed an entire subgenre, spawning hundreds of imitators and creating a line of novels still immensely profitable today, or boast of never being out of print for what is now close to a century. Georgette Heyer is one of these authors. Not entirely by design, she ended up creating the Regency romance, making her name synonymous with the subgenre, and if her later followers have added considerably more sex than she would have approved of, they have very carefully followed the world she created.
