To call this thorough would be a gross injustice. It's meticulous to a fault, at least for the novice that I am. Reading other (shorter) books on the subject and going over course material from grad school helped me navigate the latter parts of the book a little better. I highly recommend it to anyone who would like a very in-depth look at puritanism and its ramifications in early New England, but you do need to have a solid background in European, and especially English, history and theology to digest all the information.
