Worldbuilding in Paranormal Romance

I've taken a big departure in my normal writing material with my latest contract from Carina. Darkest Caress is a paranormal romance, and the first of a trilogy--if my readers like it enough to warrant me writing the next two books.

I just received "developmental edits" (short for please beef up your worldbuilding) for it from my awesome editor, but I have to admit I'm very daunted by the prospect of diving in. I've never written PNR before, but I've read my fair share. The little kernel of an idea for this series came to me during my trip to the Baltic States two years ago with my favorite cousin. The characters in the book are magical beings that have descended partly from ancient tales of folklore at a special part of Lithuania I visited, known as the Curonian Spit. It was a spooky, breathtaking and magical place, part beach resort where the Soviet Beaujolais spent their summers, and part dark, twisted woods where witches and demons are said to still exist.

It was too good to pass up, plot-wise. I couldn't help myself. Plus my crit partner is a fantastic PNR author with a major trilogy coming out from NAL next year, and she kept bugging me to write a PNR, because it was "hot" with the romance market and surely I'd be able to snag an agent, where my military romance had not. And so Darkest Caress was born. In the end no agent wanted it, but thankfully Carina Press liked the core of the story enough to offer me a contract. 

While I wade through these edits, I want to try to make sure I avoid cliches or things that turn readers off of PNR, if possible. Do any come to mind for you? I recently saw a thread on a discussion loop where readers were complaining about how sick they are of PNR in general, especially vamps and weres. Well, my characters are neither of those, but I still want to steer clear of any landmines if I can help it.

Anything bug you/bore you with PNR today? Please share.
