Book recommendation?

My daughter's husband has been assigned to RAF Lakenheath for two years and they will be here the middle of October. They have three young children ages 8, 4 and 2. The two older children are boys and the youngest is a girl.

I am hoping that somebody can recommend a book(s) for my daughter that explores the differences in terminology and culture between the UK and the US. Part of the requirement is that the material is not too heavy as she wants to use it to prepare the kids for some of the differences and get them excited about the move.

My daughter and her husband have lived in Germany for several years (my ex was Army and his dad was Air Force) so they are no strangers to learning and adapting to different cultures but the kids have never lived outside the US.

Anybody have any thoughts?
