The Last Voyage of Poe Blythe is a standout for its antiheroine. Poe, who has never had much to begin with, lets rage and anger steer her actions after raiders killed the boy she loved. But what she thinks is a straightforward path to vengeance turns into a twisting trail of self-examination and assessing everything she thought was true. Poe is a pull-no-punches type of girl, which readers will appreciate. She's blunt and emotionally detached, and not in the "brooding but charming" way other books portray similarly strong, haunted characters. I've seen it labeled as fantasy, but I don't know that I would call it that. It's presumably set in the future, but one that has regressed to more basic technologies after attempts to expand resulted in the withdrawal of central support when it became clear the Outpost was too difficult to maintain. There aren't any fantastical elements, just the notion that the old is gone, and this is society trying to rebuild itself.
