My favorites are Jude Deveraux and Johanna Lindsey (which you mentioned). If you haven't read "Love Me Forever" by JL, you must! Its my favorite, or for a different twist try to find that book in audiobook format (unabridged). The narrator does the accents perfectly and its great listening!
Also, Amanda Quick writes great historicals, she just put out a new one about a month ago. Judith McNaught is a good one too, she has both historical and contemporaries. If you haven't read a LaVyrle Spencer book yet, you should, she has great stories. The two I recommend are the Gamble or Hummingbird.
PM me if you want some more suggestions or would like to talk about them! I'd love to talk about the books, but all the discussion boards I've found for them have ppl that take things a *little* too seriously.
