By the light of a suit lamp, the others were already eating. They sat around suit backpacks that glowed green, giving off light and warmth. Breakfast was a slab of sticky, green, manufactured by a backpack from the organic produce of this world’s ocean, washed down by a visor-full of water.

On staggering into this sea-shore cave Hex had inflated her own suit to form this bubble-tent. If you looked carefully you could see the suit’s seams, even one stretched-out glove. Inside, the crew had stripped off their suits, pooled their backpacks, and slept, lying on one stretched-out suit while blanketed by another. They had needed time for some essential maintenance, of themselves as much as their suits.

In the mouth of the cave, beyond their shelter, a fire burned fitfully, hampered by poor convection in the low gravity. Oddly the flickering glow of the fire seemed more human than the pale green of the suit lights, but it had been built by an utterly alien being.

It was odd for Hex to have her crew together like this. She had spent most of the last year with them, but for most of their time together they were sealed up in their blisters. Now here they were, stripped down to their heated undergarments, all crammed in. Borno, the only man, was bulky, big-boned, hard-muscled. She imagined him spending hours honing his body so he could take down Ghosts hand on hand if he had to. Hella was smaller, thin, morose and anxious, but possibly the smartest of the three. Jul looked a little overweight; maybe she had been skimping physical exercise. Of course the fact that the lower half of her body was a clunky prosthetic didn’t help.

And then there was Hex - the youngest, she uncomfortably reminded herself.

Borno groused, ‘We’re interstellar warriors and we’re reduced to this. Stuck in a cave like animals. You can’t even tell if it’s morning or night.’

‘It’s always day here, dummy,’ Hella said. She sounded tired, drained; she chewed on her food tablets without enthusiasm.

‘Lethe, you know what I mean. It’s morning somewhere . . .’

Restless, Hex made her way to the wall of her suit-tent. They were in the northern hemisphere, but the cave was oriented south, so she could see the twin suns, a glum red blur with that spark of bright blue crawling over its face. It was strange to think that the double star never moved from its station in the sky, as if nailed there. The ground was worn, a thin soil lying over the melted bedrock that was all that had survived a supernova torching. The air was less than a fifth Earth’s pressure: too thin for them to breathe, but enough to transport sufficient heat around the planet to keep all the water, and indeed the air itself, from freezing out on the dark side.
