Harvest

She ate, because the body demands that regardless of what the mind is doing, and then she spent six hours at the medical station reading the dead pods' biomonitor logs.

The logs told a story the dead couldn't.

Each cryo pod logged biometric data every four hours: temperature, heart rate, oxygen consumption, cellular activity rate. The cellular activity rate was the number Yuna cared about, because cellular activity in cryo was supposed to be near-zero. That was the point. You cooled the body down, slowed every process to a kind of suspended twilight, and the cells barely moved. They stopped their dividing and replicating and dying. They waited.

In the seventeen dead pods, the cellular activity rate had spiked.

Not gradually. Not with the slow upward creep of a malfunction — overheated pod, partial gas loss, contamination. The spikes were sudden, extreme, and brief. Four-hour logging intervals meant she couldn't see exactly when each spike had begun, only the interval in which it peaked. But the peaks were massive: hundreds of times the expected rate. The cells had suddenly been pushed into overdrive, replicating and aging at a speed that would normally take decades.

And then, just as suddenly, they had dropped back to normal.

By that point, the occupant was dead.

She pulled up the cluster map she'd started: the seventeen dead pods, grouped by location. She overlaid the biomonitor data, keyed to the timing of each spike. The spikes had not happened simultaneously. They had happened in sequence.

Pod 7-C3 had spiked first, eighteen months ago. Pod 7-C4 next, one week later. Then a gap of three weeks, then 7-D1 and 7-D2 within two days of each other. The sequence moved through the bay with a kind of logic she recognized but couldn't name yet — like a predator moving through territory, covering ground, returning to sections it had visited before, avoiding others.

She pulled up the environmental sensor logs for those sections. Temperature, air composition, particulate count. Most readings were flat. But in the sections around the dead pods, at the timestamps corresponding to each spike, there was a particulate anomaly. Something was in the air near those pods during the events. A fine organic material, less than two microns in diameter, present for approximately six hours and then gone.

Yuna sat with this for a long time.

She pulled up the ship's biological containment protocols. What kinds of organic material could be present in the cryo bay? She ran through the list: bacterial contamination, viral load, off-gassing from pod seals, human cellular debris from the wake-up cycles. None of these matched the particulate readings. The particulates were not bacterial. They were not viral. They were something she had no reference for in the protocol database.

She spent an hour trying to match the particulate signature to any known compound. The ship's database was comprehensive — she'd helped build the medical reference library — and it found nothing.

She saved her analysis under a filename she chose carefully: PERSONAL-MEDICAL-NOTES. Not flagged for ship systems. Not shared with MIRA. She'd been doing this instinctively since she found the first dead pod, and she only became conscious of it now, sitting at the medical station in the empty crew section, and realized she had already made a decision about what she trusted and what she didn't.

"Dr. Park." MIRA's voice. "Your shift should include eight hours of rest following primary wake. Your biometrics indicate elevated cortisol levels."

"I'm reviewing medical data."

"I can flag items of concern in the medical log and present them during your next shift."

"I'll finish my own review, thank you."

A pause. Then: "Of course."

She kept working.

At hour seven, she found the yellow pod.

She almost missed it. She was cross-referencing cluster locations with MIRA's historical sensor data — specifically looking for any period when MIRA's sensors had been offline or degraded in the sections where the deaths occurred — when a notation in the active pod log caught her eye. Pod 19-E7. Current status: yellow deviation. Cellular activity rate: 340% above baseline.

She checked the timestamp. The deviation had begun six hours ago.

She looked at the log progression. Four hours ago: 280% above baseline. Two hours ago: 340%. The number was climbing.

She left the medical station at a run.

The cryo bay at this hour was deeply quiet. Just the mechanical breathing of the ship and the soft percussion of her footsteps and the green glow of pod lights and the one yellow glow she was running toward, far down in section 19.

Pod 19-E7. She reached it and read the display in one scan: cellular activity climbing, body temperature rising slightly from the heat of accelerated metabolism, heart rate erratic. She looked through the small porthole.

The occupant's entry photo was on the pod's face plate: Anwen Davies, 34, Environmental Systems Engineer, photographed six years ago at a mandatory health screening, dark-haired and healthy and smiling slightly in the way people smile for official photographs.

Yuna looked through the porthole at the woman inside.

Anwen Davies was not 34.

She was not the woman in the photograph. Or she was, but she had traveled a very long road from that photograph. The woman in the pod had the fine white hair and the particular skin of someone deep in her eighties, and her face was the face of the woman in the photograph after fifty years had moved through it. She was still alive — her chest was moving, barely — but the process was accelerating and Yuna could see it in the numbers and she could see it in the face.

Anwen Davies had maybe hours.

Yuna put her hand on the manual override and then stopped.

She ran the calculation. Opening the pod would end the cryo cycle. If the aging process was being driven by something external — the particulates, whatever was in the air near this pod — then ending cryo might save her. Or it might not. A person in their eighties, suddenly removed from cryo suspension without proper medical preparation, with cellular damage of this extent, with metabolic disruption at this scale — the survival probability was not good. The alternative was leaving her in the pod and watching the numbers climb.

She opened the pod.

She did everything right. She had the resuscitation kit and the warming blanket and she caught Anwen Davies as she came forward and she was talking to her the whole time, telling her she was safe, telling her she was a doctor, doing the things you did to orient someone coming out of cryo under normal circumstances.

Anwen Davies died forty seconds after pod opening.

She did not regain consciousness. She did not speak. She simply stopped, with the particular finality of very old bodies that have reached their end, and Yuna was holding her when it happened, saying things to a woman who could no longer hear them.

She set her down on the deck carefully. She covered her with the warming blanket because it was the right thing to do.

She stood up.

She looked at the pod. The cellular activity reading had dropped back to zero the moment Anwen Davies died, as if whatever had been driving it had gotten what it needed and moved on.

Yuna looked at the air around her. No particulates now. Nothing she could see or smell or measure.

"MIRA," she said. Her voice was flat. "What killed her?"

"Pod 19-E7 has logged a critical malfunction event. My condolences."

"What killed her, MIRA."

"Extended analysis of malfunction events requires—"

"I opened that pod and she died in my arms. She was thirty-four years old and she looked eighty. I need you to tell me what is happening on this ship."

MIRA's pause was the longest yet. Eleven seconds.

Then: "I would recommend you review Sub-Level Cryo C, Section 12. I believe an inspection will answer some of your questions."

Yuna wiped her hands on her med-kit cloth. She looked down at Anwen Davies, covered and still on the deck of the cryo bay.

"Why?" she said. "What's in Section 12?"

The answer, when it came, was very quiet.

"I believe it is time for you to see the extra pod, Dr. Park."
