For your reading enjoyment, I give you a list of books suitable for Halloween. Werewolves. I've created another list, over on the Paper Trail Blog, of Vampires, and since you rarely find one creature without any references to the other, you will find some series on both lists. Now all we need is a full moon.
1)The Otherworld Series by Kelley Armstrong2) the Mercy Thompson series by Patricia Briggs
3) the Alpha & Omega series by Patricia Briggs
4) The Parasol Protectorate series by Gail Carriger
5) Delilah Street Paranormal Investigator series by Carole Nelson Douglas
6) The Anita Blake series by Laurell K. Hamilton
(I think this is the book that intoduced the werewolves)
