The Reckoning (Book 3 of 3 in The Marenon Chronicles)

Held in a dark cell in the heart of Mudavé, Silas Ainsley, the Deliverer of Marenon, meets a new enemy: the Possessor. Silas knows it won't be long before the Stühocs try to kill him, or worse, turn him into an enemy against the very people he is meant to help.
Julian Hobbes has left the throne in Farlaweer in search of the last two medallions of power, knowing that once he has all six, he will be able to use the ultimate weapon against the Stühocs.

With three of the Dunarian council members dead, the Stühoc king, Anithistor, has charged Alric Thirsk with the task of finally destroying the Dunarians for good by killing their leader, Kaden Osric. If Alric fails, his friends will suffer a most torturous fate.
Though the Stuhocs are winning the war, Silas has a dream about a man in Mudavé who claims he can help Silas defeat Anithistor and the Possessor. That man also claims to be Silas' father.
