The Templar Knight

Swedish author Jan Guillou follows up the highly acclaimed The Road to Jerusalem with the second book in his Knights Templar trilogy.
The Knight Templar follows Arn's adventures in the Holy Land, where he discovers that the infidel Saracens aren't as brutish and uncivilised as he had been led to believe, and that in fact there is another, darker side to the teaching of the Cistercians.
