This is the penultimate part of Blue Ice. Anton deGama is in the rings of Saturn, planting bio-engineered plants on a chunk of ring ice, when he sees blue snowflake creatures moving towards him. He describes what he sees to Kellerman as the creatures approach.
"You think they're some form of bio-tech sabotage, Anton?"
Anton shook his head, and then realised that she could not see the gesture. "Not really. I think they're some kind of rogue svenskites." Anton was staring at his blooms and their approaching demise. "We brought life into the rings, Kellerman. Svenskites, draxblooms, anazites, even singleships." He tiptoed carefully through the draxflowers, trying to use his shadow to hold back the blue tide. It was like using a bucket to put out a forest-fire. "Maybe this life has been here long enough to grow a few predators."
"In forty years?" He could have cut Kellerman's disbelief with a laser.
"Nearer sixty – the first svenskites must go back that far. Hard radiation, genetic changes... and the need to survive, Kellerman. Living beings grab hold of life pretty tenaciously - why should that be different for the life-forms we engineered?"
Next time, the final snippet, as deGama responds to what he has found.
As always, comments appreciated!
