England and France are locked in a brutal struggle for power. The fate of the embattled duchy of Normandy is in the hands of the weak and untrustworthy King John. Facing disaster, he calls for help from a former outlaw - Robin Hood.
The most powerful fortress in Christendom, only Château Gaillard can resist the French advance. Robin and Alan must defend this last bastion against overwhelming force - for if the Iron Castle falls, Normandy will fall with it. 512pp
