Guard at the Gates of Hell (Gladius Book 1)


George Olney - 2016
    The Empire, the structure that held civilization together for a thousand years, is collapsing. Trying to hold things together is the Corps of Imperial Gladius, one of the pillars originally created to support and protect the Empire throughout its long life. A Gladius is a genetically bred ultimate soldier, the best soldier that ever existed. Despite that, the Emperor, a deeply paranoid sociopath, fears the Corps and is trying to destroy them, regardless of what that will do to the Empire's security.A surviving portion of a devastated Gladius legion arrives on the isolated and decadent world of Cauldwell to be confronted with the fact they must once again take up their ancestral trade, war. The appearance of the legion is probably the most newsworthy event on Cauldwell for the last century and star reporter Shana Ettranty decides to do a series of stories about them for her network. That decision radically changes her life when she decides to undergo Gladius recruit training to get a better perspective on the Corps. As she continues, Shana learns deeply buried secrets about Cauldwell... and about herself. Those secrets will change the course of human history. In the end, they destroy the Empire.This is a military science fiction book written by a retired Army officer whose viewpoint has ranged from being in the ranks to general staff, not just an action book. The story asks some very tough questions about survival and sacrifice made to let humanity survive. In it, the Corps and Shana are forced to make some hard decisions. Are their answers right or wrong? In the end, only the reader can decide.

The Rise of Daan: Chronicles of Daan: Book 1


D. Ward Cornell - 2021
    You’d think that would be a good thing, but in truth, not so much. You see, a Protected World is a sentry world. One located along the edge of human space, there to sound the alarm if there’s an alien invasion. A world that is marginally habitable, so unlikely to be a target, yet well connected to the rest of humanity, so able to sound the alarm.And that’s the real problem. Marginally habitable worlds can’t support a significant population. And for the few of us that live here, it’s difficult to scrape out a living.You might ask why anyone would want to live in such a place. I ask that question all the time. The short answer is that these worlds were given away to anyone that had the means to claim and settle them. A lot of adventurers couldn’t resist the opportunity. My grandfather, six generations back, was one of those people.There are many stories about my ancestral grandfather. He was apparently quite a character, eccentric as well. Many of his sayings are built deeply into our culture, and most involve the number six. Spend a day in town and you’re likely to hear them. ‘Better to do one thing well than six things poorly.’ Or ‘better to have six good days than one good week.’Of his many sayings, there’s the one my mother quotes all the time. ‘The sixth son of the sixth generation will stand above them all.’Well, it turns out that I’m the sixth son of the sixth generation. My father, and all his forefathers, were first sons of first sons down the line from the great Jared Daan. I was my father’s sixth son. Sixth son of the sixth most direct connection to our founder. My parents gave me the name of my ancestor, Jared Daan. I’m the first to bear that name since the great man passed. My mother says I’m destined for greatness. I think that’s crazy talk. But my five brothers hate me for it.
