Calla Falling

Vampire hunter Calla has spent her life fighting bloodsuckers, just like all the women in her family before her, and she's enjoyed every second. But when vampires come out of the coffin, the hunter's Council orders her to play nice. It's an order she'd rather not take, but the Council is all she's ever known.

Though she misses the feeling of a stake in her hand, Calla is willing to accept her new way of life, until she's blackmailed by the ancient and annoying beautiful vampire, Isolde. Urged by the Council to comply, Calla must pretend to date Isolde in a scheme to endear vampires to the human public.

Calla promises herself she will do everything she can to undermine Isolde, but the longer she spends with her the harder she finds it. When she learns of a threat to all vampires, she must decide if she will help the woman she swore to hate but never could, or deny her heart and follow her training.
