I love seeing all the paranormal/fantasy/sci fi book addicts here! If you like Karen Marie Moning, try her Fever series. Also try Thomas Sniegoski's Remy Chandler series if you like fallen angels.
Ilona Andrews had a couple of great series too.

Here's some of my favs:
Sherrilyn Kenyon's Dark Hunter series
Jeaniene Frost's Night Huntress series
Lara Adrian's Breed series
Nalini Singh's Psy-Changeling series
Rachel Vincent's Shifter series (awesome series!)
Faith Hunter: Jane Yellowrock
Oh, and for historical romance, you can't go wrong with Diana Gabaldon's Outlander series!
I also like a lot of young adult series because sometimes I just don't want to read page after page of sex lol
Julie Kagawa - Iron Fey
Cassandra Clare - Mortal Instruments
I get a lot of good book recommendations from Goodreads and Library Thing. Look me up
