The Invisible Conflict Chronicles

In thirteenth-century Hungary, Baron Levente is dying from an illness Bishop Konrád believes to be a curse. His former pupil, the knight Rodger Clement, must seek a cure in the Bükk Mountains. But a hidden struggle for power is already unfolding as the kingdom rebuilds after Mongol invasions. Clement is ready to risk his life for his lord; the remedy he pursues may awaken a danger far greater than the disease.
