The Wyvern's End - John Broughton - Bog

It is AD 726 and King Ine of Wessex, tired of rebellion and internal strife, makes a pilgrimage to Rome. In an announcement, he decides to leave his kingdom to someone younger and thus, the door open to contending rival factions.
Among the young men with a strong claim to the throne is Aethelheard, Caedwalla's son: a brave warrior and brilliant strategist. To secure the throne he has to overcome other aethelings encouraged by the wayward nun, Wynflaed, engaged in a personal campaign of revenge with Aethelheard's mother Cynethryth, Abbess of Wimborne.
The third novel in John Broughton's 'Wyrd Of The Wolf' series, The Wyvern's End is an epic tale of faith, ambition, and treachery, where the fates of kingdoms hinge not only on battles, but on the unseen maneuvers of those who walk the shadowy halls of power.
