Do you know of any books involving nobles, supernatural creatures – romance?
Laurell K Hamilton’s Merry Gentry Series has several different kinds of supernatural creatures and Merry is a Princess of the Unseelie Court. It also has other nobles of the Unseelie Court, the Seelie Court, The Slaugh, The Goblins, and The Pixies. It also has romance but not traditional romance. J. R. Ward’s Black Dagger Brotherhood has vampires and has a semblance of nobility to it, but not as obvious as the Merry Gentry Series but more of a traditional romance storyline.
