I shamefully have the first book of the Temeraire series from her, that I have yet to start reading sob but I might begin with this. I'm glad it feels more adult than YA, though, since YA just puts me off hah

Ahhh both options sound fun! Though I think I'd be most inclined to mashing their worlds together to make up a new setting? :>

And also: would you be interested in writing it in a gdoc? I've been doing that recently, especially for slow-burn, world-build-y stuff and it's really working great.
