Hard Drop


Will van der Vaart - 2013

But what they find, hidden deep in the tunneled passages under the city, will change everything about what he fights for and what he believes in. With the unit in tatters and loyalties divided, the choice he makes in the dark will seal all of their fates - and much more besides.

Excalibur's Quest (Swordships Odyssey)


Dietmar Arthur Wehr - 2018
    Humanity is now at their mercy, but not all Space Force warships have been defeated. Wolfe Koenig’s light cruiser, Excalibur, is on a mission to acquire technology that just might enable the ragged remnants of the Fleet to snatch victory from the jaws of defeat—if he can find an alien race with that technology, if he can convince them to trade for it and if the technology can be exploited fast enough. Excalibur’s Quest is the story of that mission and the challenges, both alien and human, that Koenig faces. This is the second book in the action-packed military SF Swordships Odyssey series. Genre categories: space fleet, military SF, space opera, galactic empire, alien invasion, first contact, space exploration.

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.

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.
