The Age Of Cinna: Crucible Of Late Republican Rome (Historia   Einzelschriften) - Michael Lovano Full Disclosure: I am a good friend of the author, with whom I endured graduate school at UCLA.

That said, this book remains a good, solid reappraisal of those final decades of the Roman Republic just prior to Julius Caesar's rise to power. It's definitely not for the general reader - it's my friend's PhD thesis and, thus, assumes a knowledge of late Republican history and languages both ancient and modern that would daunt all but the specialist.
