Victory, finally! About Thieurrul, don't worry: Hellguard (alternative name for that world) is being abandoned by the Grand Fleet. So fast they're killing their own civilians (heads will roll when the Senate hears of this).
Read the entire series, it's worth it. And don't worry, the Romulans won't do that again. Just look at their reaction at Shinzon: as long as he fought the Federation they were OK with it, when they figured out HOW the Two Worlds garrison waited for him to be away from Romulus and then started moving (from Shinzon's reaction and Donatra's confidence, I think they were just the first wave and the rest of the Grand Fleet was coming or moving to intercept).
Oh... No, I was talking about the Rihannsu series. It includes: My Enemy, My Ally (in which we meet commander Ael and find out about what corrupt elements of the Romulan governement are doing); The Romulan Way (in which we see about the society of the Two Worlds and how it came to be, and Ael makes a cameo in the end to prove not all Romulans lost their honor); Swordhunt (in which we see an attempt to prevent the Second Romulan War and the last plan of the Romulan governement. Was originally published as the separate novels Swordhunt and Honor Blade); The Empty Chair (in which the Second Romulan War and the Romulan Civil War have erupted, and Ael, with Kirk's help, has to defeat the governement before it's too late).
