Some personal favorites:
- Your Money Or Your Life
Great book on financial independence and simple investing. Get the 2017 version since they made modifications to their investing recs to be less bond centric.
- I Will Teach You To Be Rich
The name is gaudy IMO, but the contents are very rational and cover pretty much all the foundations of personal finance, from investing to budgeting, to enjoying your life. The name feels like a get rich quick thing, but it's about what the other describes as "living your rich life" - essentially enjoying your money in addition to saving and investing for the future.
- The Simple Path To Wealth
Great simple investing book. Probably the best investing book for the average person, in my opinion. Well written, to the point, and rational.
There are some other great books out there, but those are three solid ones to start with. I Will Teach You To Be Rich is the most catch all based on what you're looking for.
