A solid little non-fiction beginning reader.  On the one hand, the topic may seem more suited to older students, while the text and format are definitely targeting beginning readers, but it will still have its uses as a beginning introduction to civics in the United States.  Where as some beginning readers tend to over-simplify information for the sake of simplifying the text, this one manages to convey a clear and concise explanation of the three branches of the Federal Government, explaining the division of power, and the ways the power of each branch is limited by the others.  The text is limited to 1-3 sentences per page, well-supported by relatively up-to-date color photos.  Though it certainly doesn’t go into great depth, it does capture the basics.
