If you are an american I recommend the federalist papers. Not exactly an edge of your seat thrill ride, but gives you a glimpse of what was being argued when the constitution was written. Which is good thing do to have when every politician and news outlet is lying about it.

At this point they are basically free but even buying a copy new is like $10.

I'd recommend the Anti-Federalist papers as well for a more libright take.
