The Burning Stone

Fleeing the massacre of his entire family save a single uncle, young Roman aristocrat Quintus Varrus arrives in fourth-century London not knowing who is to blame for the murders nor whom he can trust now. He fears for his life, but when he meets a young Irish woman named Lydia Mcuil, their lives quickly become intertwined and her father offers to set the young Roman up as a smith (under an Irish alias) in the town of Colchester while the young lovers get to know each other from a distance.

But the assassins haven't forgotten Quintus and a deadly ambush is barely thwarted, bringing the young Roman into friendship with his rescuer, a hardened former military policeman known as Rufus Cato, who has his own score to settle with the powerful man behind the attack. Quintus is introduced to the secrets of an ancient brotherhood that is trying to halt the rot that is destroying their beloved Empire--secrets that may finally reveal the identity of those who murdered his family, and expose the shocking reason why.
