Fun and informative. I particularly liked the inclusion of what was going on in the world during the good rulers' reigns and the what living during the bad rulers' reigns might have been like. It added some fun global context. I enjoyed the sidebars of information, though I think they had more information than the actual text sometimes, so I feel that the formatting there was an interesting choice. All the same, the context added a lot. I also appreciated the caveats included in the bad rulers' section, saying that different records have different opinions of those rulers, and that it often depended on the biases of those writing the records.
However, the very first section is about Hatshepsut - awesome! - and in the "When Hatshepsut was Pharaoh" section, it says that "the chariot was the vehicle of choice in the civilized world," and I object strongly to the use of the word "civilized" in this context.
Overall, it's a great way for kids to learn about some fun historical facts about some interesting rulers. Might be a good hook for kids who need the entry into the subject.
