England in 1360. The Pestilence is killing thousands, undermining the authority of Church and king. Cemeteries are full, burial pits overflowing. Prayers beseeching God's mercy, remain unanswered. Unceasing horror...
But there is worse to come. More deaths and increasingly brutal murders. When Bishop of Hereford, John Trilleck, is beheaded, Pope Innocent sends Cardinal Beyssac and his companions to Hereford to restore the Church's authority. Their journey through England reveals a lawless country, rife with paganism and ritual murder.
The disciples of the Wyvern Ring will wade through blood to fulfil their sacred duty. As emissary of the pope, Cardinal Beyssac is targeted for assassination. Deadlier than the Pestilence, it appears the Wyvern Ring cannot be stopped.
