First Among Equals (Paperback) (ISBN-13: 9781838360146)

This is an alternate history story set at the end of the Roman empire. The empire has split into three competing segments.

Now Gaul faces its biggest threat yet. The Arabs have humiliated the Eastern Empire, conquered North Africa, and invaded Spain. Their raids threaten the heart of the empire.
