F as in Frank by David A. Page is a murder/mystery detective story set in Boston, in which one of the police detectives (the title character) happens to be a werewolf. It’s gotten some pretty good reviews on Amazon.com, although I haven’t yet read it myself. It’s on my list though.
Laurell K. Hamilton’s Anita Blake, Vampire Hunter series has two main romantic leads vying for Anita’s love: JeanPaul, the vampire and Richard, the werewolf.
Personally, I’m rooting for the werewolf. I just can’t seem to overcome my personal bias against dead people.
No-one’s mentioned Brian Stableford’s “Werewolves of London”?
And would a Buffy novel featuring Oz count?
