Dave Ramsey's book - Total Money Makeover
I think this is a very good, easy entry into the world of personal finance and financial responsibility. He lays out some very good tips on starting your budget and path to financial freedom. I really like his "emotional wins" take on personal finance: his steps have you do some things that aren't driven by cold hard logic. At a very high level his book is centered around how to get out of debt and save for retirement, using real life stories from his radio show as examples. It is a VERY easy read, and can probably be finished in one or two sittings. You can expect a more in depth review of this title in the future.
