Well written enough and jammed full of facts that you are not likely to find elsewhere. You may or may not like some of the personal details about some of the main players, depending on whether you think they distract from the main story line or add color to it. The guy's obvious contempt for Ronald Reagan made me distrust the narrative somewhat: he literally could not find anything good to say about Reagan. Of course, that doesn't mean that there was actually anything false in the book; only that it is likely that Rosenfeld was being somewhat selective with his facts.
