What a great story. Do you like secrets, personal issues, inner strength, moral questions, intelligence, ideals, reality checks, diverse casts, overwhelming odds, tragedy, family, and superheroes? Read this. The pace is measured, until it gets intense, the relationships felt real, and it is character-driven. They drive the plot, and it is very satisfying. I have a few quibbles, but first and foremost, I'm delighted to have read this.
There's no getting around the self-referencing in third person internal dialogues, but it's So Many Words. :) For some reason, Yael's musings were the worst - not because of pronouns, but because xe seemed the most childish, somehow. I'm assuming it's a temperament problem, intentional, and will be sorted in future stories. Other reviewers have mentioned the misgendering - but it is addressed, and by Yael, in xyr own time, and that seems right to me.
Bonus: the worldbuilding is top-notch, filtered in via the characters - I feel like I've been there. It wasn't entirely comfortable, the more I learned, which is just brilliant.
