I love books, but sometimes you can get bogged down with all the wording and you just want a diagram to show you. This book is well illustrated. It is easy to read without being patronising, but also for the academics out there it covers some more in depth themes. My friend loves all this stuff so I have bought it for a present- but I keep reading it! Good value too, cheapest I've seen it was £10 at a halfprice book event in my supermarket. I would recommend this to anyone aged 13- 103. Well written.
