Tormented (connected by Jackson Spey #4)

Rahenna doesn't want to be a wicked vampire bitch. But she can't help it. This lovely elder has been stricken with a mysterious infection. As "out of sorts" as she is, Rahenna summons the will to provide protection for one of her fledglings recently turned mortal, the gorgeous Adin Swift, as he celebrates his first real birthday in over six hundred years.
It proves to be a very strange party, in a number of ways. After Rahenna and ancient vampire Rugh rout the evil undead trying to crash the birthday celebration, it's time for some sexual healing . . . vamp-menage style.
