Bad Metal 01: Wrecked

by Robert Black

In 2031, a viral pandemic swept the globe, indiscriminately devastating all forms of complex life. The human and animal populations were decimated within months. The developed nations of the world each blamed one another for releasing a bio-weapon, either out of malice or incompetence. In 2035, the world saw its first nuclear war.

Circle of Retribution: A Future Chronology Short Story (Future Chronology Series Book 6)

by D.W. Patterson

SABOTAGE!“You first,” said Maxine, “I want to watch you to get an advantage.” “Okay,” said Gardener, “here goes.”The flight suit was similar to the old wing-suits used on earth. A web of material between the legs allowed the pilot to run on the ground and use his legs for stabilization when in the air. Another web of material extended from each arm tapering into the body at the waist creating a triangle. The arm material extended as much as two feet beyond the fliers hands. Unlike the old wing-suits, Titan's flight suits had active compensators built-in to help maintain proper flight attitude. This kept the suits from rotating around the fliers yaw axis as was common with wing-suits.From the top Kitty Hawk sloped downward in all directions. Gardener consulted the heads-up d...

Their only chance of survival is to uncover the secret of the mysterious object, but that too seems hopeless – because no trace of the transporter’s constructors can be found...

Faster

by K. Anderson Yancy

Survival of The Fittest

by K. Anderson Yancy

In the late 1980’s, it was hypothesized that all humans had a common mother who lived 200,000 years ago in Africa, “Eve”. Subsequent to that study, another came out that traced all living humans to 27 mothers believed to be the survivors of an apocalypse untold thousands of years ago. Looking around, we can see the similarities within one another as well as the differences from developing in such diverse environments. What might happen if two groups of humans separated by an apocalypse on two different solar bodies survived and flourished each in their own way? Survival of The Fittest explores that.
