With the direction the stock market has been going recently, it's gotten me thinking about beginning to invest some money for the future and ultimately for my retirement. I'm 20 years old and have been working full time this fall at an internship and have been making enough money so that my savings account has actually been growing. I'm interested in starting a Roth IRA, but would also like to get my feet wet in the stock market with a little bit of money so I can get a feel for how it all works before I graduate college.

Unfortunately, I don't feel my knowledge of the stock market, or just financial planning in general is at the level where it should be. I was wondering if anyone knew of some good books that I should look into for sound investing techniques? I'm sure there's lots of books about the topic, but I'd like to hear if any of you have and recommendations.

Thanks for the help, it's much appreciated.
