It's a comic book written by a reporter, talking about the history of journalism and its successes and failures. It's surprisingly in-depth, going into the various biases involved in journalism and in democracy, and going through the characters involved in journalism (notably I.F. Stone and Helen Thomas, although sadly not covering Judith Miller and the appalling job she did).

I'd recommend it, but only to someone who was really interested in journalism and democracy -- if you're expecting entertainment over education, then a) this is not the book for you and b) you're a big part of her thesis.
