I have three for you:
1) The Undercover Economist, by Tim Harford
2) Freakonomics, by Levitt and Dubner
3) The Economic Naturalist, by Robert Frank
Of the three above, The Undercover Economist is the most broad using rational, real life, and current examples to explain modern macroeconomic concepts. The most entertaining to read is Freakonomics which uses economics and quantitative measures to explain events of recent years and comes up with some very surprising, previously unthought of, answers. The Economic Naturalist explores various social/economic questions that pop up on ordinary people's heads and provides economic answers for these questions.
Also, you may want to try Thomas Sowell's Basic Economics. An excellent synopsis, but a little too doctrinaire for my tastes.
