We will be discussing the second of the two Julius Caesar novels by Rex Warner:
Imperial Caesar
Both can be had as a joint eBook: Julius Caesar: Containing 'The Young Caesar' and 'Imperial Caesar'. A brief review at Bookish.
Mention was made in the last chat that this might be "all military," but so far in my opinion the military parts are more concise and for the non-military mind certainly less annoying than in Colleen McCullough's "Caesar: A Novel."
