Great read!
Format: Kindle
In addition to being an engaging lecturer, Stoermer writes beautifully! “Again and again, people confronted the distance between the compact as advertised and authority as exercised.” Gorgeous prose and achingly painful history.

No Index or footnotes
Format: Paperback
I have been following Prof Stoermer’s videos preceding this book and pre-ordered it on that basis. I to read it but am a bit disappointed and disturbed that there is nothing by way of an index or footnotes, and no reference I can find that they are available elsewhere. My 3 therefore, has nothing to do with the substance and will update this review after I read it. But I don’t understand the absence of such material.
