*A New History of Greek Mathematics*

I have read only about 30 pp. so far, but this is clearly one of the best science books I have read, ever.  It is clear, always to the point, conceptual, connects advances in math to the broader history, explains the math, and full of interesting detail.  By Reviel Netz.  Here is a brief excerpt:

And this is how mathematics first emerges in the historical record: the simple, clever games accompanying the education of bureaucrats.

One of the best books of the year, highly recommended.
