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. The bad news is that planets fit to live on are scarce-- and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding.Earth itself is a backwater. The bulk of humanity's resources are in the hands of the Colonial Defense Force. Everybody knows that when you reach retirement age, you can join the CDF. They don't want young people; they want people who carry the knowledge and skills of decades of living. 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.

The Star Brotherhood (AGU: SC Intelligence #1)


Thomas DePrima - 2013
    The team, introduced in Book 4 of the A Galaxy Unknown series, and with small roles in subsequent books, is now featured in their own story as this AGU: SCI series kicks off. This story is a mix of low-tech and high-tech as shootouts in saloons and city streets vie with spaceship chases and space battles to dominate the pages of this book. Space Command Intelligence operates to the full width and breadth of Galactic Alliance space— and sometimes beyond. Intelligence gathering is a dangerous profession, and most agents operate alone, or with a single partner, but there are exceptions. Trader Vyx, originally a lone field agent, was saddled with two information gatherers when he left the Gollasko Colony, but mutual bonds of respect soon grew between the three men. When two female operatives were rescued from Tsgardi slavers by Vyx, Byers, and Nelligen, SCI temporarily assigned the women to Vyx's team. Now, years later, the team is still together, and operating as one of the most effective groups in SCI.With the defeat of the Uthlaro Dominion, their former territory has fallen into anarchy. Space Command doesn't have adequate resources to bring the region under control while facing other enemies on multiple fronts in Regions One and Two, so SCI agents have been sent in to do what they can.Trader Vyx and his team are on the planet Bleadalto, two hundred light-years from Uthlarigasset. Their mission is to assess the situation there and learn everything they can about the slavery problem, but the once out-of-control-violence situation on Gollasko seems like a tea social compared to everyday life on Bleadalto. Within hours of arriving on the planet, Vyx is forced into a gunfight with a Brotherhood thug. The large crime organization is not pleased.

Crystal Soldier

Revenger


Alastair Reynolds - 2016
    Planets have shattered and been remade. Amongst the ruins of alien civilizations, building our own from the rubble, humanity still thrives. And there are vast fortunes to be made, if you know where to find them.Captain Rackamore and his crew do. It's their business to find the tiny, enigmatic worlds which have been hidden away, booby-trapped, surrounded by layers of protection—and to crack them open for the ancient relics and barely-remembered technologies inside. But while they ply their risky trade with integrity, not everyone is so scrupulous. Adrana and Fura Ness are the newest members of Rackamore's crew, signed on to save their family from bankruptcy. Only Rackamore has enemies, and there might be more waiting for them in space than adventure and fortune: the fabled and feared Bosa Sennen in particular. Revenger is a science fiction adventure story set in the rubble of our solar system in the dark, distant future—a tale of space pirates, buried treasure, and phantom weapons, of unspeakable hazards and single-minded heroism and of vengeance...
