If anyone is interested in Roman historical fiction, my dad has been writing a series called The Imperial Archives along with two one-shot books on characters met in the series:

What does a teacher do when confronted with a garden full of Praetorian Guards? Claudius Numisius finds out when he accepts a mission from Caesar to search for an unknown people who are reputed to possess a mysterious ability, an ability
Caesar wishes to appropriate for the Empire. How far will Claudius go and what will it ultimately cost him? Orphaned siblings and a psychopath intent on using a weapon of horrific consequences cross the teacher's path and threaten the success of his mission. Whether it is Gaul, Germania, or Sicilia, wherever Claudius goes, it seems that death will follow.

Inexplicable disappearances have plagued a province in the eastern Empire for almost a quarter of a century; occurring at maddeningly regular intervals, but neither a clue nor a reason have ever been found to explain anything. A mysterious and unknown city and a shadowy figure may reveal the motive behind the disappearances, but can Claudius unravel the secret before it threatens the existence of the Empire?

How does a girl find her way in the Empire that she calls home, but one that she does not feel at home in? Julia Scipionia and her family are uprooted and moved across the Empire for a chance at a better life. It seems, however, that a better life was meant for everyone except her. Julia is a troubled young woman until she finds someone who helps her to discover who she really is. The path she takes is not an easy one; along the way, she will endure happiness, heartache, mayhem, and murder.

How does a young woman from Germania become the most powerful leader in the world? Liesel Daunhauer’s path to that title is one that she did not seek; one that takes her from her home in Germania to the Mosel River and the Teutoburg Forest. A path that forces her into close contact with the Seleucids; the ancient enemy of the Empire that will stop at nothing to destroy her and any Imperial citizens that get in their way.
