This is probably not the best intro to economics book (i.e. it is a little too concise in places), but I liked it nevertheless. Overall, the author did do a great job explaining ideas given that it was intended to be so short. I feel like I have a much better understanding now of why the quality of life is so different between "rich" and "poor" nations. The main draw back is that there's little to no iteration i.e. I usually learn by being exposed to a concept or term several times but in this short book there's no room for that - you're told about a concept once (if at all). Regardless, this book is interesting and does makes you want to learn more about the subject, so I think you ought to give it a try.
