I LOVE Bertrice Small! She's my favorite romance writer. My favorites by her are The Love Slave, the Kadin, Adora and Skye O'Malley. I also love Kathleen Woodiwiss, especially The Flame and the Flower and The Wolf and the Dove. I haven't read Shanna since it came out back in the 70s/80s, but I remember that I really liked it.
Right now I'm reading Drawing Down the Moon by Margot Adler. I read it when it first came out back in 1979. This is the latest edition, which came out in 2006, so it's a completely different book from the one that I read almost 30 years ago.
