What's "What we pretend we can't see" about?

So I have an extremely long commute to work and was looking for a podfic to listen on the way. I saw the fic and the length is good (10+ hours - nice for several days) but I couldn't find what the fic is about anywhere.

I just wanted to know whether it has angts (I would love that) or anything I should know.

Thank you!
