Knowledge and the Wealth of the Nations

The title of the book is misleading. I would suggest: "How and why Paul Romer saved Economics" or "Paul Romer, the new Adam Smith"...This would reflect the general tone of the book. The book is, in fact, a history of recent Economic Thought on Growth, but David Warsh tries to convince the reader that everything before Romer was just a sketch of his 1990 and 1996 papers. Anyway, it worths reading: lots of gossips and an a quite comprehensive view of the recent debates about the theory of economic growth.
