Insatiable (2010) is the latest from Meg Cabot, of Princess Diaries fame, and the first book in a new series aimed more at the adult paranormal romance market.
Meena Harper is a writer for a popular soap opera with an odd personal ability. She can tell exactly how everyone she meets is going to die, despite really not wanting to be able to.
Lucien Antonescu is a professor who also happens to be a Romanian vampire prince. He enters Meena's world when visiting New York to unravel the mystery of which rogue vampire/serial killer is draining his female victims.
Insatiable is long on interesting character development, and not just in terms of Meena and Lucien. The supporting cast is well-developed, too. I particularly enjoyed Alaric Wulf, part of the Palatine Guard, created by the Catholic Church to fight demons--at least in this book.
Overall, if you're looking for a fun, quirky paranormal romance read, you can't do much better than this one. Just keep in mind that, being the first book in a series, the ending definitely lacks resolution.

My overall personal rating of Insatiable is a B+.
