Imperium, a novel of ancient rome, is the next great novel from Robert Harris which plays in the time of Caesar, Cicero and Pompeijus Magnus. It shows the way of Cicero from first getting a senator and his way upwards in the hierarchy of ancient Rome. A major point is the process against Verres.
Personally, I really loved this novel. It's one of the best titles from Robert Harris. It is perfectly combinig fictional elements with real history.
