Heart of Stone by Tom Jolly (Analog, May-June 2021)1 opens with what turns out to be a group of sentient asteroids (who call themselves “Stones”) seeing a flash of light in the rock field they inhabit. After discussing the matter between themselves (they think a younger member of their species may have mixed a hazardous “hotfire” that caused it to explode), one of their number, Five Rings, goes to investigate. During this, something wet hits it:
I sent harvesters out for the fluids and found that much of the internal material was organic. It was surprisingly warm, warmer than our own internal fluids. There was both water and organics, mixed together, much like our own minds and cells. Some of the outer covering was organic, too, but didn’t taste the same; it looked like it had been made, like some object we might excrete on our own stony surface. It was flexible. Had this Thing been alive? Regardless, the resources were too valuable to waste. As we spent water to propel ourselves on occasion, we needed to replenish it when we could, and the Thing was an excellent resource. I wondered if there were more Things available. It would save me from having to chase after every wayward comet that fell our way, putting a rock into its path and hoping some of the scattered ice shards would come my way, so that I might gather and store them for the future.
I broadcast my findings to the others, and the ones with close vectors propelled themselves in my direction, keeping a sharp eye out for more Things. p. 28
After this the narrator changes to Heart of Stone, who tells the rest of them2 that he has detected another Thing, and is setting off to intercept it (although some of the others advise against this course of action). When he approaches the Thing (spoiler) it waves at him, and it becomes apparent (to those readers who didn’t suspect previously) that the Things are human astronauts. This second astronaut tries to communicate with Heart of Stone before trying to make it to a wrecked spaceship nearby:
I reabsorbed some of the warmgas, knowing that I wouldn’t need to escape an attack from the Thing, and ignited the rest, following the Thing to its rendezvous with the new bit of scrap.
Would this be another living thing?
No Sense Of Humor was nearby, and said to me, “That Thing is going to miss its target. If you wish to help it, you must get in front of it.”
“I have little fuel to spare,” I said. This was a common lie, since few Stones would allow themselves to get so low that they could not maneuver. That would mean a slow death, perhaps even consuming the core’s water to chase after more volatiles. It was a subtle request for help, whether actually needed or not.
“I can toss some ice to you when I am nearer. If you garner some benefit here, I expect some sharing,” said No Sense Of Humor.
It was a good response. I sparked some more warmgas and accelerated beyond the Thing’s position as it flew toward the scrap, and used simple steam to position myself in front of it. More volatiles than I would normally use in two cycles, but it seemed so important. I really was hurting for propellants. It was so rare that we ever needed to move anywhere quickly, and so expensive.
We flew past the debris together, the Thing coming down on my Stone, and then I accelerated slowly back toward the debris. The Thing seemed content to ride on my surface, though it kept pointing the shiny nob of its outer surface at me. I did not know what that might mean, but the Thing did not seem frightened. p. 29
The astronaut eventually gets to the damaged ship—but only after fighting off alien scavengers that attack it and Heart of Stone (we learn that Stones are created by groups of scavengers occupying empty asteroids and becoming a single sentient creature). When the astronaut is finished examining the wrecked ship, he or she goes and lands on No Sense of Humour, who has just arrived at the scene. Subsequently, there are further attempts at communication during which the human gives No Sense of Humour a torch. Then the human dies—either from their injuries or damage to the suit (the scavengers caused a couple of leaks during the attack).
The penultimate chapter sees the Stones detect an even bigger ship (it appears the one that exploded was a scoutship) and, after another debate, they decide to contact it. Finally, the last chapter is related by Diamond Eye 16 cycles after this First Contact, and describes the events that have occurred subsequently (as well as giving us an insight into the novel formation of this solar system).
This is an original, inventive, and enjoyable piece.
