I'm a total urban fantasy/paranormal romance junkie, Sookie is my favorite but there are some other good series too.
Succubus Series by Richelle Mead - Vampires, succubi, angels, and demons are the type of creatures in this book.
Mercy Thompson Series by Patricia Briggs - Shape shifters with a female "coyote" as the main character.
There is another thread in the Book Club forum for Laurell K Hamilton - she has a series with vampires - I'm not a huge fan but some people really like her work.
Kate Daniels Series by Iona Andrews. I started this book but didn't have the time and never finshed. I've read reviews that the series gets so much better after the first book - I believe there are a range of creatures from witches to vampires is this series.
Fever Series by Karen Marie Moning - This is a must read if you haven't already. The creatures are human and fae.
Black Dagger Brotherhood - J R Ward. Vampires - this series is pretty long and each book focuses on one of the vampire characters and him falling in love. There is also a long story arch carried through the series. I really liked the first few books but got bored after a while.
There are two other places that I have found that have a lot of discussion about this genre of books besides goodreads.com. I lurk on the sookieverseblog for book suggestions - it's on their forum under general - off topic - books. Obviously the members on that site are huge sookie fans and discuss a lot of other related books. The other site I find suggestions are charlaine harris's official site. On the forum she does a "book and blog" where she reviews a variety of books, usually one being urban fantasy. Also on that site members discuss other paranormal romance/urban fantasy recommendations. If you go to her website, click on community forum - other writers, you will see an extensive list of other authors in that genre.
