Speak Daggers to Her — Rosemary Edghill

Karen Hightower (aka "Bast") is a single white witch living in Manhattan, working as a freelance graphic designer while reading tarot cards on the side. But when a close friend dies mysteriously, Bast must turn detective to find out why.

Bast's investigation leads her through the cults and covens of New York's occult underground -- in search of a killer who may have black magic on his side.
