That’s really great! Congrats.

If you can do an Amazon/Audible integration, that would be awesome (and will let you build your recommendation system?).

From experience, I like to read the most populars/iconics books outside my perspective/pov, even though, if I had to grade them, it wouldn't be 5/5.

Maybe though, the most problematic of theses "ideological bubbles" is that people don't generally want to escape it.
