I finally finished Harrow the Ninth by Tamsyn Muir. It was an effort. This is the sequel to Gideon the Ninth, a science-fantasy gothic space opera locked room mystery, which I adored, but the sequel was a slog for me.
The parts of Gideon which I loved (the voice of Gideon, the self-deprecating genre-aware humor, the overwrought gothic setting, the action) were much less present in Harrow, and the parts of of Gideon that I had trouble with (confusing plot, giant cast of characters and their tangled web of relationships) were much more present. Harrow is a very confusing book - intentionally - but I'm not sure the author pulled it together in the end. I'm still not quite sure what happend or why, though the final chapters do try to untangle the mystery for the reader. I may not be the audience for this type of book.
