A Tangled Road to Justice (Paladins of Distant Suns #1)


Olan Thorensen - 2019
    When former soldier Everett Cole signed on to help colony planets prepare for joining the Federation, his employers were disconcertingly vague about their identity and his duties. Yet, the pay was good and it got him off Earth and on the way to a fresh start. More reservations arose when - 11 light-years from Earth - he met his partner, Edgar Millen, an enigmatic man with a penchant for violent solutions and a fetish for the mythology and language of the American Wild West. It wasn’t until they reached the colony world of Astrild that the mission became somewhat clearer. They were players in multi-faceted efforts to steer colony worlds in preparation for joining the Federation. Unfortunately, not all obstacles were amenable to diplomatic, political, or economic solutions. Cole and Millen were agents, troubleshooters, hired guns - or whatever you wanted to call them - tasked with removing impediments to civilized law and order - the methodology left open-ended. Millen and Cole’s first mission to test their partnership? The backwater town of Justice was under the control of a strongman and his henchmen. All they had to do was convince the cowed citizens to rise against their tormenter. Formal authority and backup? None. Millen was blasé at the assignment. Everett’s first thought was, “What the—!”

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....
