Favourite Feminist or Strong Female Lead Sci-Fi Books?

Finishing up Octavia Butler's excellent Lilith's Brood trilogy of Dawn, Adulthood Rites, and Imago.



It's an epic story about an alien race that saves some humans from Earth's annihilation during the nuclear war and who have plans on how to return the humans back to Earth, but that it comes with a caveat.

The first book focuses almost exclusively on the point of view of Lilith. I'm on the 3rd book now and it's been amazing. Each book focusing on different perspectives as the story goes on.

I've read the Atwood, loved the dark Handmade's Tale and a few others, but wanted to check in with you. What are some of your favourite feminist or strong female lead sci-fi books/series?
