Excellent tome on The Final Solution, focusing (of course) on Auschwitz, the foremost concentration camp in The Third Reich, if one counts by the number of dead. Rees has researched the subject for many years, and even facts from the 21st century are included here. Apart from the sheer chronological dealings, Rees exemplifies, factualises and explains everything in lay-person terms, going to great extent to bring out the humanity of it all, i.e. how humans are at their worst and best in a variety of ways, before, during and after WWII. A must-read, as a brilliant accommodation to the likewise brilliant BBC TV series.
