Anyone who has seen The Lion in Winter will remember the vicious, compelling world of the Plantagenets and readers of the romance of Robin Hood will be familiar with the typecasting of Good King Richard, defending Christendom in the Holy Land, and Bad King John who usurps the kingdom in his absence. But do these popular stereotypes correspond with reality?

In this sweeping narrative, celebrated historian Frank McLynn turns the tables on modern revisionist historians and shows these larger-than-life characters as they really were - crusading, fighting vicious wars in France, negotiating with the papacy, engaging in ruthless dynastic intrigue, often against each other: in Richard's case, even holding the kingdom together when fighting in the Holy Land; and in John's, losing Normandy, catastrophically agonising the barons over Magna Carta and losing the Crown Jewels in the Wash.
