Tales from the Lyon's Den


Chris KennedyDoug Dandridge - 2018
    But mercs of all species know that if you head to southwest Houston, near the Starport, there’s a particular run-down strip mall that looks like it’s been abandoned for years. The glass door second from the south end of the strip is plastered over on the inside with blue paper, and the faint golden outline of a rampant lion is the only clue. The door is locked, of course, and beyond the door is nothing but a darkened hallway with a downward slope and a slight curve to it. Once you follow this curve far enough, you are greeted by two very large, very well-armed Lumar. “Welcome to the Lyon’s Den,” the larger of the two says without a translator, and without a trace of an alien accent. “You know the rules?” 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. Edited by bestselling authors and universe creators Mark Wandrey and Chris Kennedy, “Tales from the Lyon’s Den” includes eighteen all-new stories in the Four Horsemen universe by a variety of bestselling authors—and some you may not have heard of…yet.

A Fiery Sunset


Chris Kennedy - 2018

They’ve fled, leaving Sansar Enkh to go to the Mercenary Guild headquarters on Capital Planet to stand trial for humanity. On the run, Jim Cartwright and Nigel Shirazi have travelled to the Winged Hussars’ secret base of New Warsaw, in an effort to convince Alexis Cromwell to join the fight, while the other mercenaries who escaped the fall of Earth have gone to the perceived safe haven of Karma. Alexis Cromwell is reluctant to commit to an unwinnable fight, though, and there is no safety to be found in Karma. When the Mercenary Guild Tribunal is revealed to be a sham, the Horsemen are forced to choose—is it better to hide and protect the Human race, or is it time to fight for what they believe in?

Into the Looking Glass


John Ringo - 2005
    But there was no radiation detected, and, when physicist Dr. William Weaver and Navy SEAL Command Master Chief Robert Miller were sent to investigate, they found that in the center of the destruction, where the University's physics department used to be, was an interdimensional gateway to . . . somewhere. An experiment in subatomic physics had produced a very unexpected effect. Furthermore, other gateways were appearing all over the world and one of them immediately began disgorging demonic visitors intent on annihilating all life on Earth and replacing it with their own. Other, apparently less hostile, aliens emerged from other gateways, and informed Weaver and Miller that the demonic invaders, the name for them that humans could most easily pronounce was the Dreen, were a deadly blight across the galaxy, occupying planet after planet after wiping out all native life; and now it would be Earth's turn, unless Weaver and Miller could find a way to close the gateways. If they failed, the less belligerent aliens would face the regrettable necessity of annihilating the entire Earth to save their own worlds. . . .
