We actually purchased these books and read through all of them. They are fantastic, I highly doubt those who left one star reviews actually read these books and are just hateful people who choose to keep the masses ignorant of what this country was founded upon.
More to the point, the one star negative reviews on here are wrong...I actually purchased the full set, kids, tweens and teens and none of them...NONE...have inappropriate imagery. Those who claimed inappropriate imagery need to be specific about which book and page number. Otherwise they are guilty of slander and GOOGLE should be held accountable for perpetuating the one star reviews "misinformation!"
