This is part four of Blue Ice. Anton deGama is in the rings of Saturn, planting bio-engineered plants on a chunk of ice the size of an ocean liner, when his colleague Kellerman sees something blue moving on the ice. Anton moves towards it...
Anton needed a successful harvest to stay in business. He had chosen draxblooms because they were tried and tested – they would not give a large profit, but the bio-tech was well-established in the rings and was a safe option.
"DeGama? What are you doing? Talk to me, groundhog!"
He checked his footing as he replied "I'm not losing my crop if I can help it, Kellerman. Keep your scope on me and warn me when I'm close."
"You're close now, dimwit! Get out of there, DeGama! Get back aboard the Rose and survey it from space!" Anton could hear Polestar's contralto rising in pitch as the ship responded to Kellerman's mood.
All logic dictated that he get off the ice-cube. Anything abnormal was dangerous. He resolutely ignored common sense, and kept moving.
Sorry - still no reveal of what Anton is facing. Maybe there will be the start of an answer next time... As always, comments appreciated!
