Between a Witch and a Hard Place

Twelve years ago, my mother, a powerful chaos witch, walked out on me and my twin brother without a backward glance. We didn't hear another word out of her until a vampire walked into my brother Nick's bar wanting me to track her down. She'd disappeared into thin air, and he insisted that I was the only one who could find her.
Of course, I refused. How could I not? Disappearing was Mom's wheelhouse, and after she'd disappeared on us, I never wanted to see her again.
Then members of the local supernatural community started turning up dead, and Nick was fingered as the suspect. With his life on the line, I had to make a choice: Throw everything I had at finding the real culprit and, maybe, our mother, or be forced to watch while the local werewolf pack tore Nick limb from limb as punishment for a crime he didn't commit.
