Quickening, Vol. 1 — Amy Lane

Little Goddess: Book Five
Volume One

Cory thought she'd found balance on Green's Hill -- sorceress, student, queen of the vampires, wife to three men -- she had it down!  But establishing her right to risk herself with Green and Bracken had more than one consequence, and now she's facing the world's scariest job title: mother.  

But getting the news that she's knocked up takes a back seat when a half-elf hunts them down for help. Her arrival brings news that the werewolf threat, which has been haunting them for over a year, has finally arrived on their doorstep -- and it's bigger and more frightening than they'd ever imagined. 

Cory throws herself into this new battle with everything she's got -- and her men let her do it. Because they all know that whether they defeat this enemy now or later, the thing she's most afraid of is arriving on a set schedule, and not even Cory can avoid it.  The trick is getting her to acknowledge she's pregnant before she gives birth -- or kills herself in denial.
