Houston, 2030: The Year Zero

by Mike McKay

This novel is both a classic police detective and a social science fiction. Or, you may call it a dystopian warning. As the name suggests, the action happens in not-so-distant future. The detective part is thrilling: an FBI Special Agent follows a serial killer case. In the science fiction part, the reader will not find any robots, or flying cars, or super-computers. The end of our world does not come from zombies raised from the graves (although one “zombie” is positively present.) There are no viruses that kill a person in under thirty seconds (although, there are viruses that positively can kill.) There are no continent-size volcanoes, asteroid showers and aliens from outer space, and no Noah's Flood (although one flood is positively present, but very local.) Does not sound too scar...

The Contact Episode One

The ascendancy of mankind is being decided on Jupiter
In the 22nd century, mankind assimilated the Solar System within the orbits of the inner planets, and was gradually moving further out, beyond the asteroid belt, onward towards the outer planets. The recently discovered technology of remote manipulation gave people the capability of altering the orbit of celestial bodies of planetary size, which laid the foundation of a new era for the human race: the terraforming age. The colonization of space beyond the limits of the Solar System became only a matter of time. Soon after the first successful test, changing the orbit of Mercury, a strange object moving from the depths of space towards the centre of the Solar System entered the f...
