The Motley Fool Investment Guide by David Gardner, Inc Motley Fool, Tom Gardner (2001, Paperback, Revised)

I found this book very helpful. My first investment experience was unfortunate. Now I understand why. This book shows the importance of reviewing a companies financials and how to interpret that data. It helps you discern between the risky don't do it unless you are insane stocks and the stocks that could truly blossum into a stock worth having. The book I purchased was a few years old but the info is still relevant. I am sure that a newer book would be equally beneficial.
