This is kind of a strange story starting with now. Colonel Mitch Williams was a former Marine jet jocky who became a ground-pounder and then was disgraced from the service. He met up with some friends and other discarded military that were led by another disgraced office, Admiral Millie Narayan. They all joined together to form the Riggers. The Admiral is now dead and so are quite a few of the Riggers. But now they are on the asteroid called Asimov and have joined or incorporated the former members of the Knife’s warriors. They need to plan their next steps.
Their situation is also now complicated by the fact that the pedophile Corporal Watson turned out to be a Tetron and a very dangerous one at that. He exemplifies the serious trouble with the Tetron. They have been infected with a virus that was supposed to give them human emotions, but it got twisted and the Tetrons turned on their human masters. Watson is now leading the Tetrons and he’s even more twisted than all the rest. His ultimate goal is to enslave all humanity and then kill every one at his leisure. Colonel Williams has become Watson’s number one enemy and Mitch feels the same for the slug named Watson. Mitch’s problem is that he doesn’t know exactly where Watson has gone, but he does know that the other Tetrons are headed for Earth and their intentions are not good!
Watson has stolen the Goliath, Earths first FTL starship and one that Colonel Williams wants back. Yet, the Knife’s assets at Asimov were plentiful, so he can get to where he wants to and that’s a place called the Black Hole. It’s there that he hopes to find a scientist that might be able to figure out some code that will kill or disable all the Tetrons. He needs to find this scientists location, get there and secure him and then get to Earth before the Tetrons. If he doesn’t succeed in doing all this, there might not be an Earth to return to.
So the war continues. The final showdown is coming, but you have to remember that time travel is involved and what could be the end of everything isn’t necessarily the end. Figure that one out.
