Galatea was originally part of a collection of myth retellings called xo Orpheus, published before SOA took off (it lists a bunch of authors on the cover, Madeline Miller is part of the “and more”). It’s worth checking out if you can.

I’m in the same boat as you - I read Circe first and right after the birth of my first child at the start of the pandemic so it really resonated with me. I’d read a few feminist Greek myth retellings so I had a pretty negative bias against Patroclus and Achilles going in which probably didn’t help.
