I loved the Horrible Histories when I was a kid. In fact, I was reading them long past the age they were aimed at. However, coming back to them as an adult what really stands out to me is that Deary doesn't cite any of his sources. I have no idea if any of what he writes in these books is true or where he got his information, so they are pretty useless as educational tools. I guess they are meant to be a jumping off point to get kids interested in history in the first place. All of that sounds very general, but I don't really have anything to say about this book in specific even though I just read it. Sure, some of the stories in it were interesting and I would like to know more, but since I don't know where any of this information came from, I can't. Great for kids, don't revisit as an adult.
