Surprise because I have hated every previous Hugo-nominated Sarah Gailey thing I've read ("STET" and River of Teeth).

Which one is STET? I have had mixed experiences with Gailey; I loved Magic for Liars and found The Echo Wife deeply insightful about its characters, in a horrible way. Didn't get much out of Upright Women, beyond a strong vibe of "written for someone who is Not You."
