Not a rip-roaring ride, Witches is still a well written and researched historical treatise. Beginning with a summary, Schiff then dedicates most of the book to the available resources, which is quite surprising how dense it is considering the sources are somewhat limited to court documents and personal diaries. What can be occasionally quite dry, but nonetheless very informative becomes far more interesting when you get to Schiff's concluding chapters where finally her own voice and interpretations are offered.
The sensationalized topic is misleading, we are dealing with Puritans here. It's not exciting but if you like history it's worth a read.
