The Hussite Trilogy by Andrzej Sapkowski (The Tower of Fools, Warriors of God, Light Perpetual)
The Tower of Fools
Reinmar of Bielau, called Reynevan, flees after being caught in an affair with a knight's wife.
With strange, mystical forces gathering in the shadows and pursued not only by the Stercza brothers bent on vengeance, but also by the Holy Inquisition, Reynevan finds himself in the Narrenturm, the Tower of Fools, a medieval asylum for the mad, or for those who dare to think differently and challenge the prevailing order.
Warriors of God
WARRIORS OF GOD, the second volume of the Hussite Trilogy by Andrzej Sapkowski, author of the bestselling Witcher series, depicts the adventures of Reynevan and his friends in the years 1427-28 as war erupts across Europe.
Reynevan begins by hiding away in Bohemia but soon leaves for Silesia, where he carries out dangerous, secret missions entrusted to him by the leaders of the Hussite religion. At the same time he strives to avenge the death of his brother and discover the whereabouts of his beloved. Once again pursued by multiple enemies, Reynevan is constantly getting into and out of trouble.
Light Perpetual
Reynevan is besieged on all sides and faces torture and execution if he makes any mistake in his quest to find his beloved, Jutta of Apolda. Aided by his companions - the ever-pragmatic Scharley and the mysterious being known as Samson Honeypot - his journey takes him all over the Bohemian realm.
And Reynevan will need every ounce of his wit, intelligence and cunning if he is to succeed in his search. The political and religious alliances of the Hussite Wars are ever shifting, and the battle for dominance threatens to devour anyone who gets in their way.
