Reddit reviews SPIN-FREE ECONOMICS

• The Undercover Economist - Has a pretty similar feel to Freakonomics. Basically economic concepts applied to every day things.
  
  
• Spin-Free Economics - More like a textbook in format. There are a bunch of short chapters on various topics which he analyzes using economic theory. Some of the Amazon reviews say it's a pretty standard free-market capitalist style thinking and not "spin-free" but it's a good primer on basic concepts imo.
  
  
• Predictably Irrational - Behavioral economics, which is basically taking psychology and applying it to econ. Basically economic models rely on humans being rational and the Ariely's research is all about how humans aren't a lot of the time. This area of econ interests me most, so if you like this book, the Upside of Irrationality, Sway, and Nudge are all pretty interesting too.
  
  
• Malcolm Gladwell's books (Outliers, Tipping Point, Blink) aren't about econ but they're in the realm of "dumbed down" interesting things.

If you're interested for your own interest and not for college, I'd recommend starting with books written for a general audience like

The Cartoon Introduction to Economics

Freakonomics

The Armchair Economist

Spin Free Economics

Lastly, Lives of the Laureates offers biographical accounts of 23 Nobel Laureates in Economics. I find it interesting since it offers insights into the minds of the Laureates, their intellectual process, and some of the most important contributions within the economics community.

I also often recommend Economics in the Afterlife to people since it shows that economists have no shame and economics can really be applied to anything.

You could probably find PDFs online of some of these books if you were so inclined.
