It is a great picture book written by two scholars, one of them even holds a Ph.D degree. And I would admit this is a first picture book I read that is written by a Ph.D. And it shows the depth without sacrificing artistic and entertaining values.
The book answered the questions raised in the title, by using maps annotated with time and events of many explorers and conquestados exploration of the New World, including Columbus, Cortes, Pizarro and Cartier. And authors threw in abundunt pictures of historical artifacts that greatly increased the draw of story telling.
Best suited for 4th grades and up audience.
Highly recommended.
