A tad overstuffed, but (because of this?) succeeds as (all of) hardboiled noir, speculative anthropology, and cathartic routing of white supremacy, which is no small accomplishment. Could have done with a more low-key ending, in my opinion, for some light and shade, but superb writing and characterisation throughout, with more than a few lines that elicited audibly-impressed noises. This alt-history nerd left happy.
