Wouldn't it be great if we could make Washington DC Invisible? Add Detroit, Cleveland, Chicago and Albuquerque to that list and the world would certainly be a better place.
Of course I have not read this book, and have no clue what it is about, but I would hope that it is a Science Fiction tale, set in the future where cities could make themselves invisible when under attack from alien invaders. If it isn't that book then Signor Calvino may want to think about a sequel incorporating that idea.
I shall wait patiently and see if he reads this and takes up the challenge.
