Let the voyages begin! Colonel Jason Azoros is having a bad year. Having taken over the Argonauts’ mercenary company when its previous owner was killed, he has arrived back at Karma to find that no one will deal with him. Blacklisted by his father, Jason is forced to do a job for him to clear his name. The early days of humanity’s expansion into space was an exciting time, as the best of the race went to the stars. Unfortunately, some of the worst went, as well, and the Argonauts must hunt down and destroy the worst of the worst, Colchis Industries. Colchis has powerful friends, though, and its coffers are overflowing with credits, allowing it to hire mercenaries and buy equipment beyond what the Argonauts can afford. They also meddle in genetics, and their creations range from...interesting...to unstoppable. Outmanned and outgunned, Jason and his crew embark on their voyage short on equipment but long on attitude. One thing is for sure - win, lose, or draw, they’re going to go out in style!

Even more authors and stories. Still the same best-selling universe. It's the 22nd century. Humanity has taken its first steps into the galaxy, and we've found ourselves in a vast playground of alien races, environments, and cultures. As the newest players on the universal stage, though, our position is readily apparent - we're at the bottom of the food chain. Welcome back to the Four Horsemen universe, where only a willingness to fight and die for money separates humans from the majority of the other races. While some of the stories inside deal with mercenaries, others introduce listeners to the other guilds, organizations, and races that make up the landscape of the Four Horsemen universe, as well as providing additional insight into the characters of the mainline novels. What's it like to be a medic on the beach or to learn how to kill from a mother not your own? Come find out! Edited by best-selling authors and universe creators Mark Wandrey and Chris Kennedy, this audiobook includes 16 all-new stories in the Four Horsemen universe by a variety of best-selling authors - and some you may not have heard of...yet. In a galaxy this big, you'll find that some of the races are good and others are bad, but only the best are mercs!
