The world-building is really interesting, but the supporting characters are ciphers. Maybe it's a side effect of the first-person POV, but everything we know about them comes from what the MC tells us, rather than from what we can observe about them from their words or actions.
Also, I didn't feel like the twist was foreshadowed, so it felt improbable and tacked on, rather than an organic part of the story.
