By day, Tess Noncoiré is a successful fantasy writer. But she has another career as well, trained by the Sisterhood of the Celestial Blade Warriors to fight demonic incursions into our world . Her partner in this fight is a sarcastic, cigar-smoking imp called Scrap. And when she needs extra back-up, she turns to rare-book dealer Guilford Van der Hoyden-Smythe -- who knows more than he should about the Blade Warriors -- and the handsome, mysterious foster child of a demon, Donovan Estevez. Together, Tess and her team weather demonic attacks, save the world from destruction, and make some powerful enemies along the way.
