The period is the Pilgrimage of Grace. In the country west of Oxford, nobles, clergy and laity await the success of the risings in Lincolnshire and Yorkshire to overthrow Henry VIII and Cromwell. Peter Pentecost is the man they plan to put on the English throne. Although a monk by training, he is the legitimate child of the Duke of Buckingham and the last of the Bohuns. His bid to be crowned and his duel with Henry VIII make for an exciting adventure.
