I bought this book on a whim, not quite knowing whether it would be another Ben Schott or not (i.e. rather dry and high brow). It is not. It is far better and great to dip in and out of. Even my kids (twins aged 9) have grabbed it for a 'look', which ended up lasting half an hour (which, if you knew my kids, is a pretty amazing length of time for them to be kept amused by one thing!).
I have now bought three more copies as Xmas presents since, to be honest, it looks much more generous a present (given it is a hardback book) than it actually costs.
I am hooked - can't wait until 'That Book 2'!
