Terminal Alliance


Jim C. Hines - 2017
    This would have worked out better for all involved if they hadn’t arrived after a mutated plague wiped out half the planet, turned the rest into shambling, near-unstoppable animals, and basically destroyed human civilization. You know—your standard apocalypse. The Krakau’s first impulse was to turn their ships around and go home. After all, it’s hard to establish diplomatic relations with mindless savages who eat your diplomats. Their second impulse was to try to fix us. A century later, human beings might not be what they once were, but at least they’re no longer trying to eat everyone. Mostly.Marion “Mops” Adamopoulos is surprisingly bright (for a human). As a Lieutenant on the Earth Mercenary Corps Ship Pufferfish, she’s in charge of the Shipboard Hygiene and Sanitation team. When a bioweapon attack by an alien race wipes out the Krakau command crew and reverts the rest of the humans to their feral state, only Mops and her team are left with their minds intact.Escaping the attacking aliens—not to mention her shambling crewmates—is only the beginning. Sure, Mops and her assortment of space janitors and plumbers can clean the ship, but flying the damn thing is another matter. As they struggle to keep the Pufferfish functioning and find a cure for their crew, they stumble onto a conspiracy that could threaten the entire alliance.A conspiracy born from the truth of what happened on Earth all those years ago…

While Ethan is still undecided about what he will do, he realizes that the Imperium has been lying and putting all of Dark Space at risk. Now Brondi's plan is starting to look like a necessary evil, but before Ethan can act on it, he discovers that the real plan was much more sinister than what he was told, and he will be lucky to escape the Valiant alive. . . .

Empire


Michael R. Hicks - 2009
    Nightmarish female warriors with blue skin, fangs, and razor sharp talons, the Kreelans have technology that is millennia beyond that of the Confederation, yet they seek out close combat with sword and claw, fighting and dying to honor their god-like Empress. Captured and enslaved, Reza must live like his enemies in a grand experiment to see if humans have souls, and if one may be the key to unlocking an ages old curse upon the Kreelan race. Enduring the brutal conditions of Kreelan life, Reza and a young warrior named Esah-Zhurah find themselves bound together by fate and a prophecy foretold millennia before they were born.

Family Law


Mackey Chandler - 2011
    Look at most of your relatives or coworkers. How lovable are they? Really? Yet most have mates and children. The vast majority are still invited to family gatherings and their relatives will speak to them. Many have pets to which they are devoted. Some even call them their fur-babies. Is your dog or cat or parakeet property or family? Not in law but in your heart? Can a pet really love you back? Or is it a different affection? Are you not kind to those who feed and shelter you? But what if your dog could talk back? Would your cat speak to you kindly? How much more complicated might it be if we meet really intelligent species not human? How would we treat these 'people' in feathers or fur? Perhaps a more difficult question is: How would they treat us? Are we that lovable? When society and the law decide these sort of questions must be answered it is usually because someone disapproves of your choices. Today it may be a cat named in a will or a contest for custody of a dog. People are usually happy living the way they want until conflict is forced upon them. What if the furry fellow in question has his own law? And is quite articulate in explaining his choices. Can a Human adopt such an alien? Can such an intelligent alien adopt a human? Should they? Of course if the furry alien in question is smart enough to fly spaceships, and happens to be similar in size and disposition to a mature Grizzly bear, wisdom calls for a certain delicacy in telling him no...

Old Man's War


John Scalzi - 2005
    First he visited his wife's grave. Then he joined the army.The good news is that humanity finally made it into interstellar space.

You'll be taken off Earth and never allowed to return. You'll serve two years at the front. And if you survive, you'll be given a generous homestead stake of your own, on one of our hard-won colony planets.John Perry is taking that deal. He has only the vaguest idea what to expect. Because the actual fight, light-years from home, is far, far harder than he can imagine--and what he will become is far stranger.

Columbus Day


Craig Alanson - 2016
    And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved. The UN Expeditionary Force hitched a ride on Kristang ships to fight the Ruhar, wherever our new allies thought we could be useful. So, I went from fighting with the US Army in Nigeria, to fighting in space. It was lies, all of it. We shouldn't even be fighting the Ruhar, they aren't our enemy, our allies are. I'd better start at the beginning....

Sassinak

Whatever it was, it wouldn't let her resign herself to the life of a slave. She bided her time, watched for her moment. Finally it came, and she escaped.But that was only the beginning for Sassinak. Now she's a Fleet Captain with a pirate-chasing ship of her own, and only one regret in her life: not enough pirates.
