Harrow the ninth

"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's health is failing, her magic refuses to cooperate, her sword makes her throw up, and even her mind threatens to betray her. What's worse, someone is trying to kill her. And she has to wonder: if they succeeded, would the universe be better off?"--
