Relatedly, The Law of Superheroes is a funny look at applying Law to pretend cases that could happen in a world with superheroes. Very recommended.

It works well for what I want, but isn't in-depth enough to really leave me feeling that I've learned law. But the law is tricky in that, afaict, it's a lot of details and unofficial know-how, so many it's not a field where a book like I describe could exist.
