This quite the impressive book. HIstorical figures are rendered as believable characters. I buy Vidal's Lincoln as a human being in a way that I can't when I am handed one of the mythological portraits of him that are so dominant. There are some major factual errors but I don't think they are particularly relevant to the plot/portrait. Also, my particular edition has some suprising typos, but I'm sure that isn't Mr. Vidal's thought. I like revisionist history in this form (i.e. fictional), specifically when it is believable, as this mostly is. A magnificent achievement despite some minor quibbles. Probably better than Burr, but I haven't read that in so long I don't really remember.
