Why has the world been waiting for this book? Well did it? You certainly wouldn't expect such a book in a regular book store, not only for the fact that they would strugle to find the right shelve for it.
Most likely the you put it on a table were random stuff lies.
It's neither a photo book nor a guidebook and certainly no cook book while it does contain a bit of all. It's a wild mix of styles while also not being a livestyle guide. So because it's something entertaining you can easily serve with a coffee, it might be a coffee table book.
