Another on one of my Fang Fictions - book 3 or 4 on the Anita Blake series; she's growing on me and I do love my vamp Jean-Claude.

This book is a (3), I enjoyed it and there is a love triangle of sorts between Richard , her school teacher boyfriend werewolf and Jean-Claude, Master Vampire and Anita starting. She's engaged of sorts to Richard but having second thoughts b/c she's realizing he's as much a monster as J-C is but in a different way, the beast within and she values her independence and is irritated when he's around after work,  she's just not ready for the big M or kids.   They are signs they are not compatible, he does not understand if she kills a bad guy while J-C does not have this hang up for he's drawn to her hard core ass. J-C wants equal time to court her, b/c she too does love him deep down but differently. This will be interesting in book 5, they have such a love hate relationship. 

The crime or crimes is about shifters and werewolves and such disappearing and Anita, Police and Edward to solving it. This one is all werewolves and shifters less Vamps thats why a (3).
