I finished my listen of Harrow the Ninth today. Its predecessor novel, Gideon the Ninth, was a sort of haunted house puzzle box body horror costume drama comedy of manners; Harrow maintains much of that, but sharply changes the narrative structure, shifting between narrators, perspectives, and points in time, in addition to stretching out to a massive, universe-wide scale. It’s disorienting and byzantine and I think it’s kind of brilliant, not only in its own right, but in the abrupt pivot in style that Tamsyn Muir pulls off in writing it.
edit: Oh! How could I have forgotten to call this out? The reading of both novels, by Moira Quirk, is absolutely wonderful.
