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
    Short on every resource but the intelligence of their personnel, Exploration Command goes where no human has gone before, discovering new worlds, species and civilizations, pushing the boundaries of knowledge, and always on the lookout for new discoveries that could help the Empire in its struggle against the invader. In this volume are three novelettes about Exploration Command, the scientific part of the Fleet. 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.
