Gretel's life has been coupled with one trauma after the next, starting with the loss of her brother at a young age and then her mentor just recently, both due to the machinations of an evil witch. Cursed with powers that grant her a long life that spans centuries, she is forced to consume human hearts to sustain herself at the cost of her own humanity.

Recently, she has teamed up with Calabar, a mercenary who is part of a secret faction determined to rid the world of all witches. But now, what they have discovered could unravel everything they have been working so hard to create. A new coven of witches is forming, and at its center a new evil rises, something so ancient that they may not be enough to protect us.
