Reading right now - Late Roman Republic

Lately I've been reading about the late Roman Republic - and watching the HBO series Rome. I started out reading the very entertaining Imperium by Robert Harris, it's a novel, but it tells the tale of Cicero's rise to power. Now I have moved on to Steven Saylor's Roma Sub Rosa
series with Roman detective Gordianus the Finder. I generally like to read a nonfiction book at the same time and so I am re-reading Rubicon - The Last Years of the Roman Republic by Tom Holland.

Another fascinating source is Plutarch's Roman Lives, which is actually very readable.
