Rampant — Amy Lane

Little Goddess: Book Four
Vol. 2

Lady Cory has carved out a life for herself not just as a wife to three husbands but also as one of the rulers of the supernatural communities of Northern California -- and a college student in search of that elusive degree. When a supernatural threat comes crashing into the hard-forged peace of Green's Hill, she and Green determine that they're the ones in charge of stopping the abomination that created it. To protect the people they love, Cory, Bracken, and Nicky travel to Redding to confront a tight-knit family of vampires guarding a terrible secret. It also leads them to a conflict of loyalties, as Nicky's parents threaten to tear Nicky away from the family he's come to love more than his own life.

Cory has to work hard to hold on to her temper and her life as she tries to prove that she and Green are not only leaders who will bind people to their hearts, but also protectors who will keep danger from running rampant.
