In the meantime, I am also reading:
The Left Hand of Darkness by Ursula LeGuin. Fascinating book, but I have to go slowly so I don't miss anything important.
The Mark of Cain by Lindsay Barraclough. This is marketed as a "companion" to Long Lankin, but it's really more of a sequel. Long Lankin is terrifying, by the way. Add it to your list.
Titans by Victoria Scott. It's like National Velvet, but with engines and oil and grease.
