With a theme of “empathic justice,” is the intent that the stories be inspiring and morally uplifting? Or is there room for nuance, in which good intentions aren’t always good enough?
I ask because this immediately made me think of Mary Doria Russell’s The Sparrow, which is about the limits and traps of empathy as a motivator for wanting to help people. It’s about an expedition to another world, led by a Jesuit priest (and is a consciously allegorical exploration of historical Christian missions). They encounter a peaceful and intelligent but non-technological herbivorous civilization, and, seeing a bit of early humanity in their situation, happily set about teaching them organized agriculture. But before long, the situation blows up in their faces, because they had incomplete information about the situation, leading to terrible consequences.
It’s a meditation on how good intentions can blind you to complex reality, and about how the desire to help can lead to tragedy if you can’t tell the difference between empathy and projection. Really tough-minded and sophisticated stuff. It might be too heady for an average high schooler (and there’s some weird alien sex stuff in the closing chapters), but a smart older teen could handle it, I think.
As an alternative, I’ll also suggest A Closed and Common Orbit, the second book in Becky Chambers’s Wayfarers series (and far and away my favorite of the four). It’s about a shipboard AI, previously bodiless, forced by complex circumstances to leave her ship and occupy a humanoid body as her “vehicle,” accompanied by a human caretaker who guides her in navigating her new life.
It’s very much about empathy and standing up in the face of injustice. The AI character is seen as less than a person by the authorities, who will confiscate and destroy her if they realize what she is, and the caretaker character also has a background where she’s perceived as less than a person. The caretaker is the only one who sufficiently empathizes with the AI, and she in turn was rescued from her own past by another shipboard AI who empathized with her plight.
True, it is the second book in the series, and the AI character’s situation comes directly out of the climax of the first book. But the background worldbuilding is pretty effectively re-established, and the AI protagonist is re-introduced, so I think the book would stand reasonably well on its own. There is some discussion of side characters going off to enjoy themselves in what are essentially orgiastic parties, but I don’t remember it being described very explicitly. I plan to give it to my SF-mad daughter when she’s 14 or 15, if that helps.
