Assumpta Mary-Margaret O'Connor's demon mark makes her fair game for any passing demon--and an attractive bargaining chip in the political alliances of Hell.
Both courted--and stalked--by demons, she realizes she'll never have peace until she rids herself of the demon's mark.
With the aid of her pendulum and the help of Brona Daly--resident ghost of Baltimore's Enoch Pratt Library-- Assumpta discovers the one sure-fire way to get rid of the mark: make a deal with the demon who marked her.
While Assumpta prepares for battle, Jak--the spirit she rescued from a demonic urn--rejoins her, bringing aid in the form of five Roman legionnaires and Saint Michael, the Archangel. Even with ghostly, and Heavenly help, can Assumpta preserver her life--and her soul--when she goes to Hell to challenge the demon who marked her?
