Act 3 has already been written, however I will not be posting it on this site.
In the 3rd act of Caesar Rising the reader will learn about Spartacus' and Sitota's past. Both men were abolitionists who fought to end slaver during their time. The reader will also learn the fate of the colonies. After the 3rd act there is an appendix which will contain information not found in Trail of Dust and Caesar Rising. The story will continue in Rise of the Meek, the sequel to Trail of Dust.
