2) Broke Millennial: Stop Scraping By and Get Your Financial Life Together, by Erin Lowry

Happy reading! Do not forget about getting your knowledge here too :)

One Up on Wall Street by Peter Lynch, The Little Book of Value Investing, and The Warren Buffett Way are great books for investing.

You can check out my summary of Warren Buffett way here, before you start reading it. Hope this helps!

The Little Book that Beats the Market by Joel Greenblatt is good, as it explains concepts in a very simple way :-) All the best
