Primal Desire by Terry Spear

Selena Townsend has no idea what will happen after she kills a fellow hunter while protecting an innocent vampiress. She’s ostracized, but acquitted of charges against her, but now she’s looking for her sister who has disappeared. That mission takes her to a vampire club and all kinds of trouble.

Atreides has been in charge of the vampire clans, while his brother is off on a honeymoon with his new mate. He doesn’t expect a huntress to walk into one of their vampire clubs, which is just not done, and then return later after being savagely attacked by a vampire. He has to take care of her before the League of Hunters learns of it, and then he wants to pawn her off on the hunters who can protect her pronto! But he finds he really doesn’t want to give her up after all.

War between the hunters and the vampires could break out any moment unless they find the rogue hunters who are killing innocent vampiresses and the vampire who had attacked Selena and other huntresses at the same time—and terminate the rogues.
