Harrowhark Nonagesimus, necromancer of Ninth House, did what she came to do. Harrow the Ninth emerged victorious to become a Lyctor to the Emperor of the Nine Houses, Ninth Saint to the Undying King. But victory hardly feels like it, trapped on a blasted space station, left without her cavalier. Forced into the fight for a doomed war to win yet another questionable prize, Harrow is discovering a struggle beyond what she has ever faced before. She has to train at the Emperor's Mithraeum with instructors she could do without. At her side is an untrustworthy rival and a sword that sickens her to hold. Worst of all, her mind seems to be fast disintegrating inside her skull. Oh, and someone wants her dead. In Harrow the Ninth, Nebula, World Fantasy, and Shirley Jackson Award nominee Tamsyn Muir continues the startling original, wildly acclaimed journey she began with Gideon the Ninth. This novel not only tells a riveting story of its own, but sets the stage for the bravura final volume of this epic trilogy.
