I'm a fan of the BBC sketch show Horrible Histories, and I also have an interest in ancient Greek and Roman culture. So this book is something I would really like to read.
And it's very nice to read. Of course is it a children's book, but it is still nice and there are still some thing in it I didn't know. It focusses more on the weird / gore (but still OK for a seven-year-old) details of history. The passages are short, and there are a lot of comics drawn next to the text. I'm quite sure I would have loved to have these books around when I was a kid.
