Book 82: Unexploded Remnants. This was a short but enjoyable book about a future world where the Earth is only a memory and a collection of artifacts. Our protagonist is a trans woman who likes to track down information about other civilizations particularly her own. She discovers an ancient AI weapon whose purpose is unclear. There's a lot of zipping around and quick meetings of other people in other species. Would have liked this book to be longer and more fleshed out but definitely enjoyed it
