The first time I heard about the series was in one of our Sonlight Curriculum Packages. That particular year the book, "Whatever Happened to Penny Candy? A Fast, Clear, and Fun Explanation of the Economics You Need For Success in Your Career, Business, and Investments" was included to read as a read-aloud. It's about economics and is a remarkably easy and fun explanation of investment cycles, velocity, business cycles, recessions, inflation, the demand for money and more. It made for fun and interesting discussions about a usually difficult subject. We still retain much of the information introduced to this day. Highly recommend!
As we continued to Homeschool, we explored a few others of the book series briefly, but was never able to get everything we wanted out of them and didn't finish the complete series. We, as adults, are NOW working our way through a review of them and reading the ones that we missed along the way. The author shares amazing insight and what seems to be, at times, a "prophetic" analysis of the world we live in!
Do yourself and your family a favor and read this series!
