I just finished this novella (Unexploded Remnants by @theelaineg.bsky.social) about a space archaeologist who finds an ancient superweapon and it was so much fun! The worldbuilding reminded me a lot of Becky Chambers. I'd love to real a big doorstop set in this universe.
Thank you! I haven't taken a free book in a while but I'm having a bad brain week and this sounds like a good distraction. (The comparison to Becky Chambers clinched the deal -- I love her books.)
