A Bloody Field by Shrewsbury — Edith Pargeter

A masterful tale of 14th century England, as fans of Edith Pargeter's The Brothers of Gwynedd have come to expect. Henry Bolingbroke, banished and deprived of his inheritance by Richard II, returns and deposes the king to become Henry IV. He is aided by powerful lords, especially by his friend, Harry "Hotspur" Percy. But his triumph quickly fades in the face of evergrowing crises. Not only is Wales rebelling, but the question of how Richard II really died lingers, causing dangerous trouble. The king also has powerful enemies poised to pounce, as he and his kingdom are drawn inexorably to a bloody collision some two miles from Shrewsbury.
