We are only 6 chapters into this book, but based on those chapters I recommend this book for grade school level children. It is a sweet, but good presentation of American History, although, definitesly NOT politically correct, being nearly a hundred years old. My children enjoy it, and are gaining a basic understanding of the founding of America.
The only reason I did not give it 5 stars is that the author managed to write a chapter about the founding of the southern colonies without ever mentioning slavery, at all, or bound servitude in the north. Perhaps it is a little too sanitized, but that might not be all bad for the age it is aimed at.
