For what it's worth, Shirer's book is sixty years old.

Richard J. Evans' Third Reich Trilogy is a recent, comprehensive history that contains tons of information that was unavailable in in the 1950s. It is unlikely to be surpassed in terms of sheer scholarship, depth, and explaining and documenting the ascent, reign and collapse of the Reich. (It's just very, very long)

In terms of how Hitler acquired power, a more current history has been written by Benjamin Carter Hett in his minor masterpiece The Death of Democracy: Hitler's Rise to Power and the Downfall of the Weimar Republic. He highlights all the modern parallels.
