A Favor for a Fiend

By Kelly A. Harmon
A Favor for a Fiend by Kelly A. Harmon digital book - Fable

Publisher Description

Assumpta Mary-Margaret O’Conner’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?
