I found the book on the whole to be quite good, even though it is more an academic book than general audience non-fiction. So, in the way of academic books he tends to have lists of other dates/times/events that are used as support to his argument, and those can be tedious. The interesting thing to me about this book, and the reason it’s only 4 stars, is that it actually ends with about 3 hours left, and those 3 hours are are and afterward, that is basically an academic clap back at another writer, and an update for 25 years after the book was written, that makes some corrections and updates the body of knowledge that pertains to his particular subject.
If you are a student of WWII or of the Holocaust, then this book is a definite, if dry and academic, must. If you are a casual listener, you might want to pass.
