I've read all three. The middle one (The Third Reich in Power) was the slowest and driest, but still worth the read. The last one was a struggle, but only because of page after page of Nazi murders. Not just the Jews, but mentally disabled, Romani, Poles, Ukrainians, Soviet Slavs, Homosexuals, people with disablities, political prisoners, leftists. It just seemed to go on and on. And it continued right to the end.
