Really enjoyed this one. Far-future galactic empires, AIs made up of both ships and people (assimilated almost Borg style), a personal quest for vengeance, and a fascinating viewpoint (that comes from both linguistic and personal aspects) where the default gender pronoun for everyone is "she/her", regardless of their actual gender. On my short list for my personal pick for the P.K. Dick award, but I still have one nominee yet to read.
