I have a textbook by Mankiw (one of the other comments here also recommends him) and it seems pretty good. I particularly like how it points out in which areas there is consensus or disagreement between professional economists and the various sides of the debate. It's expensive new but if you hunt around you can get used editions fairly reasonably.

I'd be aware that there are certain heterodox schools of economic thought that are much more popular among non-economists than economists, so it's probably worth trying to find something that presents opposing arguments and isn't too biased.

Also, I don't know about his other stuff but Ray Dalio has some great material if you want a very quick, high level introduction to some macroeconomic concepts that doesn't have much jargon. In particular I remember the introductory video at:

being pretty good. I also liked his free book on debt crises since it breaks down the macroeconomic situation in various country/time periods (inflation, government/private debt, etc) which I thought was more interesting than reading about some of those things in abstract (I also don't remember it being very jargon-heavy).
