Here's the thing: I liked this story, I like anything that has San Francisco and magic and a combination there. It's a novella that doesn't flinch away from the ugliness of the period portrayed--racism, homophobia, misogyny-and leaves a promising narrative of community and place-based magic more ephemeral. I would have preferred the combination reversed, but enjoyed it for what it was, and would return to Klages San Francisco and cartomancers within.
If you are interested but unsure about how the content is handled, I would recommend Monica Nolan for a lighter, deeply funny take on San Francisco-based pulp period romance.
