I bought this to read to my 6 year old daughter - I wanted her to get to know about history in a chronological order and this seemed like a good book to start with. When it arrived I wasn't sure how we would like it as it contains a lot of heavy looking subject matter that I knew nothing about.
I shouldn't have worried - she has really enjoyed it so far and we've been finding out new things together. The chatty style is pitched just right for her level of understanding and the chapters aren't too long. You can't read too much at once as it would get too overwhelming but we've had fun discussing topics like how archaeology works, nomads, pyramids and mummies, military dictatorships (!). The language is sometimes a little Americanised but as long as you're aware of that it doesn't interfere with your understanding. I'm looking forward to the others in the series. A minor point but I also like having the hardback version, it has a nice robust feeling to it!
