It's 1949 and the city that will be a ghetto for super-powered beings is just developing and has to deal with the growing pains of how law and order will be maintained (especially when it is filled with vampires and "former" Nazis). The book is a prequel to Moore and artist Gene Ha's Top 10 and has the same great writing and little visual jokes in the background. Colorist Art (really?!) Lyon does a great job muting the visuals so that the whole work has a dreamlike feel. I'm not sure if it is better to read this before Top 10 or right after, but don't do what I did which is have a several year gap between reading the main title and this one.
