There are many books on King Philip's War, many of which are much more well known this, but Daniel Mandell's book is the best. Why? First, the book isn't trying to make a methodological argument about the colonial period or Native Americans. It simply gives a straight forward narrative of what happened. Second, this book does not ignore the northern theater of the war with the Wabanakis.
If you want to learn about King Philip's War this is the first book you should read. The others are great, but this is the most direct history of the event.
