Kim tried to hide her frustration. “She might have been talking about a romance.”

“She said ‘we.’”

“Did you talk to Kane?”

“Of course. He maintained that nothing unusual happened. He told me he was sorry about the others, all three missing within a few days of the return, but he had no idea what had happened to them.”

She sat watching him a long time. “Sheyel,” she said at last, “I don’t know what you want me to do about any of this.”

“Okay.” His expression revealed nothing. “I understand.”

“To be honest, I haven’t heard anything that persuades me they made contact. That is what you’re implying, isn’t it?”

“I appreciate your time, Kim.” He moved to cut her off.

“Wait,” she said. “We’ve both suffered losses in this incident. That’s painful. Especially since we don’t know what happened. My mother was haunted by it until the day she died.” She took a deep breath, knowing this would be a good time to break away. “Is there anything you’re not telling me?”

He watched her for a long moment. “You mentioned contact. I think they brought something back with them.”

The conversation had already been too exotic for anything to surprise her now. But that statement came close. “What kind of something?”

“I don’t know.” His eyes flickered and seemed to lose focus. “Read the accounts about the aftermath in the Severin Valley. For years after the explosion, people have claimed they’ve seen things in the woods. Lights, apparitions. There were reports of horses and dogs showing signs of restlessness.”

Kim felt embarrassed for him, and he saw it.

“They abandoned the town,” he persisted. “They left.”

“They abandoned it because the explosion weakened a dam. The dam was too expensive to repair so the authorities just encouraged everyone to move out. Anyway people had bad memories.”

“They took down the dam,” said Sheyel, “because everyone was leaving. Kim, I’ve been there. There is something loose up there.”

She listened to the air currents circulating through the room. “Did you ever see anything, Sheyel?”

“I’ve felt it. Go look for yourself. After dark. Do that much. It’s all I ask.”

“Sheyel—”

“But don’t go alone.”

In effect, Kim and her charges, a combination of commentators, contributors, and political heavyweights, were afloat in the void at relatively close range to Alpha Maxim. They were seated in four rows of armchairs, some sipping coffee or fruit juice, one or two pushed back as if it might be possible to fall. The sun’s glare was muted. Its apparent size was about twice that of Helios at noon.

Two clocks, positioned among the stars, counted down to ignition.

Kim, in the rear, was doing a play-by-play. “The LK6 is now two minutes from making its jump into the solar core. When it does, it will try to materialize in an area already densely packed with matter.” Canon Woodbridge, seated up front, was talking on a phone while he watched.

“This alone would be enough to create a massive explosion. But the LK6 is loaded with a cargo of antimatter. The reaction will be enough to destabilize the star.”

Beside her, a technician signaled that the operation was still on schedule.

“We have a report from the McCollum that the last crewmembers have left the Trent, and that they have begun to pull away.”

One of the observers wanted to know about safety margins. How long would it take before the shock wave hit the Trent?

“There’s no danger to any of the personnel. They’ll be gone long before the first effects of the nova reach their former location. Incidentally, the Trent won’t be destroyed by the shock wave. The light will get there first, and that’ll be quite enough.”

Could she explain?

“A nova puts out a lot of photons. Think of a near-solid wall moving at lightspeed.”

The clock produced a string of zeroes.

“Insertion is complete,” she said.

“Kim.” It was the representative of a corporation that almost routinely underwrote Institute activities. “How long will it be before we start to see the first effects?”

“That’s a gray area, Ann. To be honest, we have no idea.”

There were skeptics among the witnesses, some who believed that the Institute had overreached, that blowing up a star was simply beyond human capability. Several, she knew, would have been pleased to see the effort fail. Some did not like the Institute; some did not like its director. Others were simply uncomfortable at the prospect of human beings wielding that kind of power. Woodbridge was among these. Despite his remarks the previous evening, Kim knew that his real misgivings flowed from a basic distrust of human nature.

Minutes passed and nothing happened. She heard something fall and strike the invisible floor. They grew restless. In their experience, explosions were supposed to happen when they were triggered.

The first signs of stress showed up at zero plus eighteen minutes and change. Bright lines appeared around Alpha Maxim’s belt. The chromosphere became visibly turbulent. Fountains of light erupted off the solar surface.

At zero plus twenty-two minutes the sun began to visibly expand. The process was slow: it might have been a balloon filling gradually with water. Enormous tidal forces started to overwhelm the spherical shape, flattening it, disrupting it, inducing monumental quakes.

At twenty-six minutes, eleven seconds, it exploded.

It was often possible to make a reasonable guess at a person’s age from the physical characteristics his or her parents had selected. Different eras favored different skin tones, body types, hair colors. Concepts of beauty changed: women from one age tended to be well developed, their centers of gravity, as Solly Hobbs had once remarked, several centimeters in front of them; another era favored willowy, boyish women. Men’s physiques ranged from heroic to slim. The current fashion was to consider bulk as somehow in poor taste. Males born during the next few years were going to resemble a generation of ballet dancers.

During the eighties, parents of both sexes had opted for classic features, the long jawline, eyes wide apart, straight nose. Teenage girls now looked by and large as if they’d stepped down from pedestals in the Acropolis. Kim had come from an earlier time when the pixie look was in vogue. She tried to compensate by maintaining a straightforward no-nonsense attitude, and by avoiding a programmed tendency to cant her head and smile sweetly. She also adapted her hair style to cover her somewhat elvin ears.

Solomon Hobbs was from an age that had favored biceps and shoulders, although he had allowed things to deteriorate somewhat. Solly was one of the Institute’s four starship pilots. Kim had come to know him, however, not through an official connection, but because of their mutual interest in diving. Solly had been a member of the Sea Knights when Kim joined.

He had clear blue eyes, brown hair that was always in disarray, and a careless joviality that contrasted with a culture that thought of having fun as serious business, something one did to maintain a proper psychological balance.
