Harrow the Ninth by Tamsyn Muir

Harrow the Ninth, the sequel to Gideon the Ninth, turns a galaxy inside out as one necromancer struggles to survive the wreckage of herself aboard the Emperor’s haunted space station.

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.
