I swear, you are the only person I know in real life or online who also reads these books. Even my friend that likes the Anne Rice Sleeping Beauty books can't get into these.
It's called Namaah's Kiss, I think you can get it already at Amazon. I'll buy it on the 24th at Borders, because I don't like to buy things online. It's the beginning of a new series, set in the future from where the last Kushiel book left off.
It wasn't at Barnes and Noble over the weekend, because I was there and bought a christian book (Jesus Wants To Save Christians by Rob Bell), because I couldn't find any good fiction.
