Demon Assassins Books in Order

Demon Assassins is urban fantasy romance with witches at the center and demons everywhere they do not belong. The series follows some of the last remaining demon-assassin witches, women whose job is not decorative magic but direct confrontation with hellish threats.

Colleen anchors the opening book, and she sets the tone well. She would like a quieter life, or at least a manageable one, but demons are not interested in giving her that. Her familiar matters, her friendships with the other remaining witches matter, and so does the fact that she is part of a vanishing line of defenders.

The series stretches its geography in useful ways. Fairbanks, Seattle, and even England all come into play, which keeps the books from feeling boxed into one magical neighborhood. The Sidhe connection also adds another layer. Duncan is not just a romantic complication. He represents another kind of power with its own rules and blind spots.

Across Witch's Bounty, Witch's Bane, and Witches Rule, the larger conflict stays clear. Demons are pushing harder, the witches are badly outnumbered, and every victory feels temporary unless the deeper source of the trouble can be contained.

If you want urban fantasy with a romance thread, a competent magical heroine, and a straightforward fight against infernal chaos, this series is easy to recommend. It has a brisk pace, familiar-bond charm, and enough broader magical politics to keep the world feeling active around the central battles.
