Do you like PNR?
I love the Mercy thompson series by Patricia briggs,
The Kate Daniels series by Ilona Andrews
The Kitty Norville series by Carrie Vaughn.
If you like more hard core The Mona Lisa books by Sunny aren't bad.
Everyone talks about the Breed books by Lora Leigh but they are way too much for me.
Oh, there is also the Cassie Palmer series by Karen Chance and the lupi series by Eileen Wilks.
My brother of all people introduced me to some of the PNR series and I have been tearing through them.
