I really like the "For Dummies" series of financial books written by Eric Tyson. The most basic is "Personal Finance for Dummies" and it's a well-written and easy-to-understand book that I think that any layperson interested in learning more about finance would benefit from. It gives an overview of everything from balancing a checkbook to keeping a budget to understanding mortgage rates and bank loans.
He has a whole series. Here
is a link to the other titles.
I second Larry Burkett, even though I am not a religious person and swing pretty far to the left. However, Dave Ramsey basically repackaged and marketed all of Burkett's ideas after he passed away. Burkett's stuff will seem eerily familiar if you've read Ramsey. He makes some "biblical" predictions that really were just good financial reasoning and he was accurate about a lot of things. I think this biggest seller was "The Coming Economic Earthquake" and I remember that it really got me thinking. His "ministry" (is that what it's called??) was called Christian Financial Concepts. I actually took this course of his back in the 80's/90's when I was still in my 20's and that gave me a solid foundation of financial understanding that has lasted me 2+ decades.
