Fictionalized Roman History 58-43BCE
Just finished reading (in English) Robert Harris' "Dictator" which looks at Rome from the point of view of Cicero from his exile by Julius Caesar to his execution on the orders of Octavian, Anthony, and Lepidus. An interesting way of looking at a fascinating period of history with all the famous names.
Be sure to try the first of the Cicero novels, which is Imperium. It's narrated by Cicero's slave and secretary, Tiro--an incredibly appealing narrator. I love this novel and have read it many times. The second one (Conspirata, as it's called in the US; or Lustrum, its original title) is nearly as good; I found Dictator a bit disappointing in comparison.
So, if you liked "Dictator," I predict that you'll love "Imperium" !
Do you also know Steven Saylor's series about Gordianus the Finder, a sort-of ancient Sherlock Holmes-style detective, in ancient Rome? He interacts with Cicero, Caesar, Pompey; the novels are quite engaging (and definitely as much concerned with the seamier side of things as with the movers and shakers).
