I'm always a fan of Anne McCaffrey including a lot of her non Pern related novels.
The crystal singer trilogy is good
And I really enjoyed the Petaybee trilogies.
(Power play, power lines, and powers that be) followed by the (changelings, maelstrom, deluge)
I totally forgot that there were two trilogies back to back until now... I'd been wondering how so much plot fit into just 3 books.
Note that changelings et al have to do with selkies. So that kinda resonates with transitioning.
All three trilogies have good female leads.
