Barbarians to Angels - Peter S Wells
The Roman Empire Divided - John Moorhead
The Origins of the Middle Ages - Bryce Lyon
Those are just off the top of my head. I’ll have to go into my dust filled library and find some more.
I’ve enjoyed the three+ audible copies of the Great Courses lectures on the Middle Ages by Phillip Dailaeder. In fact, audible books are really good for relief from too much eye strain.
I’ll give you one the is a very interesting revisionist view of a historical viewpoint.
G. J. Meyer — The Borgias: The Hidden History
Enjoyed it on its main subject and also its view of the period in Italy in general.
