She answered the Emperor's call.

She arrived with her arts, her wits, and her only friend.

In victory, her world has turned to ash.

After rocking the cosmos with her deathly debut, Tamsyn Muir continues the story of the penumbral Ninth House in Harrow the Ninth, a mind-twisting puzzle box of mystery, murder, magic, and mayhem. Nothing is as it seems in the halls of the Emperor, and the fate of the galaxy rests on one woman's shoulders.

Harrowhark Nonagesimus, last necromancer of the Ninth House, has been drafted by her Emperor to fight an unwinnable war. Side-by-side with a detested rival, Harrow must perfect her skills and become an angel of undeath--but her health is failing, her sword makes her nauseous, and even her mind is threatening to betray her.

Sealed in the gothic gloom of the Emperor's Mithraeum with three unfriendly teachers, hunted by the mad ghost of a murdered planet, Harrow must confront two unwelcome questions: is somebody trying to kill her? And if they succeeded, would the universe be better off?

"To read Harrow the Ninth is to enter a labyrinth haunted by loss and sacrifice and a truly top-tier selection of memes. But don't bother with breadcrumbs or red threads--you won't ever want to leave." --Alix E. Harrow

" Harrow the Ninth is a psychological rollercoaster covering forty billion light-years. It's wonderful to see the universe of Gideon expand, while staying as twisted and full of bones as ever." --Django Wexler

" Maddeningly brilliant." --Kiersten White
