It was recommended by a friend, “Economics In One Lesson”, so I ordered it.
Is there any other recommendations for beginners?

As the banking industry is a popular topic, I also recommend Rothbard’s “Mystery of Banking.” “Theory and History” is not too hard or too long of a book, and is simply awesome overall. Rothbard’s “America’s Great Depression” is also a wonderful example of an applied Austrian analysis, and is also a useful tool in discussions as comparisons to the great depression are often made for defending interventions in the financial sector.
My best recommendation for beginners:

Economics in one lesson is good, so is economics for real people (available free on the mises website).
After those, if you can handle something a bit heavier, just go for Human Action 
here are some good beginner books that helped me
paul krugman - pop internationalism, diminished expectations, the accidental theorist (this one may feel a bit more dated than others)
david friedman - hidden order
thomas sowell - basic economics
robert heilbroner - the worldly philosophers
jerry muller - the mind and the market (i actually recieved this after i graduated from undergrad and still learned a lot)
lester thurow and robert heilbroner - economics explained
thomas schelling - micromotives and macrobehaviors (maybe a little advanced for a beginner book, but still a really good read)
thomas schelling - micromotives and macrobehaviors (maybe a little advanced for a beginner book, but still a really good read)
I second this, seriously, Schelling is awesome (check out his The Strategy of Conflict too).
paul krugman - pop internationalism,
As much as Krugman deserves his reputation, this book is a must read.
