I have just published a book called "The Fall of the Republic" on the Catiline Conspiracy. While it is fictional, it adheres closely to Sallust's account and other historical sources. Here is a summary:
In 63 B.C., Catiline—an angry, corrupt politician—conspired with foreign powers and criminal elements to overthrow the Roman Republic. Exploiting those who suffered from inequality, he sought to destroy the republic in the name of the people. In the end, he nearly achieved through violence what he could not attain by inciting the masses with lies. This true story of the near-destruction of a great republic contains poignant lessons for the ages.
"The Fall of the Republic" is available on Amazon, in both paperback and Kindle editions. Use the link below or search for my name. I hope that you enjoy it!
