Resistance


Max Carver - 2017
    Rapid expansion into habitable worlds brings immense prosperity and a new age of exploration unlike any humanity has seen. WAR Conflicts over control of the colonial worlds spawn a massive, generation-long war among humans. Under a shaky armistice, humanity has just begun to crawl out of the shadows of destruction, but suspicion and bitter hostility run deep. INVASION On a rocky, desolate planet, a small band of gold prospectors find themselves making a discovery they never expected—valuable and powerful relics of the galaxy's deep past. The prospectors also discover a hostile alien species, ruthless beings who do not tolerate humans and wipe them out on sight. Humanity's first contact with intelligent aliens becomes a war for survival. The invasion has begun...but the beginning of the invasion is also the beginning of the resistance. "Resistance is a terrific space opera adventure. It combines mystery, heart-pounding action, and a good dose of humor. It's Aliens meets Tremors. I can't wait to read the sequel." -Daniel Arenson, USA Today bestselling author of the Earthrise series

The Belt: Complete Trilogy


Gerald M. Kilby - 2018
    The ship contains an experimental quantum device, lost while en route to a research colony on Europa. On Earth, powerful corporate forces are moving to resume unrestricted, inter-AI communications, their objective being to gain complete dominion over the colonized solar system. But the outer worlds are mobilizing to prevent them from achieving their objective, a fight back which is being led by Solomon, a sentient quantum intelligence (QI), also on Europa. However, once word of the crew’s discovery gets out, they soon realize that ownership of this technology could fundamentally change the balance of power within the solar system, and they now find themselves at the very nexus of a system-wide conflict. Their fight for survival plays out across the solar system, from the mining outposts of the asteroid belt to the moons of Jupiter and Saturn, and from the great Martian city of Jezero to the irradiated wastelands on Earth. This is an epic tale of humanity’s struggle for survival and meaning in a time when artificial intelligence has finally out-paced our own ability to control it. About The Belt: The story is set a century or so into the future where humanity has colonized most of the inner solar system. The asteroid belt (The Belt) is now a hive of mining activity and ships ply the trade routes to Earth and Mars. The technology depicted, for the most part, is what I consider to be technically plausible, although I do stretch it a little with quantum entanglement. That said, you won’t need a calculator or a slide-rule to enjoy the story.

Exploration Command


Doug Dandridge - 2014

In Retribution, a Command team finds a devastated alien civilization being aided by missionaries from the Empire. Or are they? In Timeless, an ancient derelict is found in a place where no ship should be. Does it hide the secrets to a technology the Empire has sought for over a thousand years? And in They Don't Care, alien species are being wiped out by a renegade race. Can a single two ship team stop them, or will more species go into the long night? For those readers of Exodus: Empires at War, these stories fill in some of the background of the Empire and add to the series. For newcomers, they are a great introduction to the series.

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.
