Lots of great recommendations here, build a list of 4-5 out of the above - then read all of them over the next 6-12 months.
You'll have a great foundation of personal finance principles by then and can begin to pivot into learning specifically about Real Estate Investing (and other semi-passive income vehicles).
The book that flipped the switch in my head was "Millionaire Next Door" (which a couple of people mentioned above). This really highlights how wealthy individuals live far below their means, and they generally own their own businesses. They're obsessed with the process, and not status. It's helpful to get this drilled into your head early, as you'll build up a mental muscle to avoid spending money on depreciating assets. When you get out of college you'll see some of your friends driving nice cars and living in luxury apartments. It is hard not to fall into the trap of status, but if you can defer that desire (for even just 5-10 years) - you'll be in a much better position long term.
If I was in your shoes, I would actually start with "Set for Life" by Scott Trench (disclaimer: I work at BiggerPockets). It's a bit more oriented to someone who is just getting out of college and in their first career job, but it sounds like you're going to be working as an agent in college - so probably pretty applicable.
