Davis consistently does what your junior high teacher probably didn't; he makes geography amusing and riveting. From early concepts of whether the world was a disk floating in water (Thales) or pear-shaped (Columbus), Davis explains earthquakes, rain forests, Atlantis and whether there are canaries on the Canary Islands. In short, he covers the scientific, physical, and political history of the Earth and does his level best to raise our collective geographic IQ while entertaining us.
