I'm guessing that most of you who clicked on this assumed that the title refers to Ioustinianos I Megas, but I'm afraid it doesn't. The title refers to this Ioustinianos, the youngest son of Maurikios who almost/may have escaped the lynch mob as his body was never found and he may have escaped the city. In this TL, he definitely escapes the city. This TL will be presented as a serialized novel, so the bookmarks will be chapters. Edit: Here's the Euratlas link for 600.
