1242. After being wounded in the Battle on the Ice, Richard Fitz Simon becomes a prisoner of Prince Alexander Nevsky of Novgorod. Alexander, intrigued by his captive’s story, instructs his scholar to assist Richard in writing about his life.

Richard’s chronicle begins in 1203, when his training to be a knight is disrupted by treachery. He is forced to flee England for Lübeck, where he begins work for a greedy salt merchant. After an illicit love affair, his new life is thrown into turmoil, and he joins the Livonian Brothers of the Sword as they embark on imposing the will of God on the pagans of the eastern Baltic. Here, he must reconcile with his new life of prayer, danger and duty – despite his own religious doubts, with as many enemies within the fortified commandery as the wilderness outside. However, when their small outpost in Riga is threatened by a large pagan army, Richard is compelled to make a crucial decision and fight like never before.
