My favorite is Alphabet of Thorn, and there's so many overlaps in narrative construction (apparently normal young woman meaningfully centered in the confluence of big political movements and even larger magics, with gentle, indulgent proto-poly vibes) but Alphabet of Thorn is about books and lost knowledge and magic schools; it has the exact personal aesthetic appeal that The Changeling Sea lacks for me. So honestly it puts The Changeling Sea at a bit of a disadvantage, but I really enjoyed it despite that!
