Gamma Ray Games: Meltdown

by H S RIVNEY

He wanted to find an old friend. Instead he found himself in the middle of an alien struggle for power. Captain Thomas Jackson takes the SS Linus Pauling crew to Tau Ceti's fourth planet when a nuclear reactor appears almost overnight where before only oil lamps lit the darkness. Technologically impossible from the culture he'd come to know seven years prior, he finds not one but two familiar alien species exploiting the resources and people of Ceti D.
Looking up the one person he can trust, a metallurgist living in the same city, he is surprised by more than just the leap of technology he finds. Things have changed, and not as he'd expected at all. When the thorium reactor is destroyed, what will he uncover that explains the value of the gamma rays it was generating?

Faster

by K. Anderson Yancy

“Ninety days has September, April, June and November…” is an antiquated rhyme because for an unknown reason, the Earth is spinning faster and faster and a day is far, far less than 24 hours and getting shorter. It’s cataclysmic, but most importantly…humanity is persevering.

The Engineer's Assistant

by Adam Middlemas

You only live once: if you’re lucky.Life was a drudge. Long hours, soul destroying work, barely keeping up with the mortgage on our “dream” home. The home we bought to raise a family in. By the time we could afford kids, we’d be too old.Modern life: chasing carrots with strings attached.Then Pete, wealthy retired chief engineer, bought the house next door. Forty years on cargo ships, he’d had lots of time to experiment. Time to build a device that would be quite amazing. If he could get it to work.Forty years obsessively tinkering. Almost working, already showing an apparently magical effect. Tantalisingly close to something so radical it could reshape life on Earth. And as close as he would ever get.But then he met me. A software engineer with a dead end job and fading dreams. I...

Devilfish: Death Eidolons: Collected Short Stores 2014 (Collected Short Stories Book 6)

by Stephen Donald Huff

Tarn is a water world, covered from pole to pole by an incredibly deep ocean. Humankind built only one city there. Situated directly on its equator, terraformers strategically emplaced this massive port to continuously exploit the planet’s boundless fisheries. Because Tarn orbits its binary system on an extreme axial tilt, each day also measures a year, and because its suns are lethal, Tarn fish only rise to its surface in the darkness. Fishing there is a dangerous business, but the planet’s entire economy subsists on the larva of a single enormous predator, which the galactic elite consume as a delicacy. Unfortunately for the common sailor, adult fish are many times larger than the comparatively tiny boats that hunt their offspring, so the death toll climbs after each six month t...
