Big interest in getting started early in law. No knowledge whatsoever and want to know what to read?

Good job! I recommend visiting laws.com maybe taking a law studies class at your high school if possible, and just reading general legal books from you library. Maybe get involved with student government. There's not too much you can do in high school. I guess watch some crime procedural to get a general feel, but remember those are dramatized. There's some good docuseries on netflix if you look for them.

Good luck!
