Peregrinations mentioned this book in one of her posts and of course I had to immediately get it. I live in a place where I am daily questioned on how I talk, and this has fostered a fascination with the English language and accents in particular.
This is a larger format book, not quite coffee table sized, but it could definitely hold its own with the art and architecture tomes. Each page features large full color heat maps, showing the prevalence for one word over another (or one pronunciation over another) in each part of the country. Some maps are mostly homogeneous ("roundabout"); some look as though someone drew a line through the country (usually an east/west line dividing north and south, of course) ("pyjamas").
MT and I had a great time comparing words and pronunciations, and laughing at the differences (and sometimes even similarities). We had fun trying to figure out his spirit state, and while it became clear that I've picked up words and pronunciations from around the country (mostly Minnesota), I was happy to see that my language still places me firmly in my home state of Florida.
An interesting look at the differences between us that are fun rather than confronting and a great conversation starter.
