Diana is a witch, though she prefers to live her life without magic. A professor of history, she wants to conduct her research in peace and is successful until a lost alchemical text finds its way into her hands. The tome is clearly enchanted, so Diana sends it back into the bowels of the library in order to keep up with her personal “no magic” rule. But the trouble has just begun. Soon, hoards of witches, daemons, and vampires join her in the library, hoping that she will once again uncover the lost manuscript. To defend herself, Diana must learn to accept and wield her inhuman gift and she quickly discovers that not all creatures are considered equal.
