My opinion veers wildly up and down depending on the chapter and the first couple were ROUGH but the later ones are largely better. Kinda like...baffled as to why Montague Summers was there but okay. 

In general it felt more like a collection of articles than a book (which considering it is written by an academic historian is not super surprising). If anything, at least read the chapter on Salem! There is so much misinformation on Tituba (down to her name, which is likely not actually that!) so it's great to see it addressed.
