Pretty interesting, actually. King got access to and found all sorts of primary source documents that had been hidden/lost/overlooked, and gives a pretty clear, if confusingly full of repeated names (think Edward or Richard in the Wars of the Roses) account of the famous feud.
Hard to keep track of, even with his genealogical scorecards showing who has been killed or wounded, but fascinating nonetheless. King makes sense of this confusing period and events and puts it all in context.
