'Who else is on the island?' her father asked casually.
'There's me and three others--two technicians and a communications specialist. We live in the houses down below.'
'With your families?'
'No families out here. We come for a three-month rotation, three on, three off. This is my fourth year. The pay's great and you get a chance to unwind from the world. Read. Think. By the way, name's Fuller. Jordan Fuller.' He stuck out a lanky hand and they introduced themselves all around.
Her father nursed his coffee. Rain battered the windows. Even at the top of the island, Abbey could hear the muffled thunder of surf on the rocks below.
'So you're up here in this station all by yourself tonight?' her father asked, stirring.
'No, there's a technician in the station. I'm sort of just security. Dr. Simic's in the station now.'
'And when does he get relieved?'
'She. Not til seven.'
'We'd like to meet Dr. Simic,' Abbey said.
Fuller shook his head. 'Sorry. Can't go in there. Off limits.'
'Come on,' Abbey said, with a laugh. 'I've been in there twice before. On school field trips.'
'Well, that's different. We get a lot of school groups. But normally no one's allowed in. Door's kept locked at all times.'
'But you can open it, right?' her father asked, rising.
'Sure I can. Why do you ask?'
Her father removed the revolver from his pocket and laid it carefully on the table, keeping his hand on it. 'Then please do it.'

The president was already standing impatiently at the far end of the Sit Room. The wall monitors were ablaze with CNN, MSNBC, FOX, and Bloomberg.com, the sound turned off, flashing images of the Moon, various talking-head astronomers, and the growing chaos caused by widespread power outages and computer failures.
Ford filed in with the rest and they all remained standing, waiting for the president to sit. But he did not sit down. The flat-panels switched over to videoconferencing mode, the images of generals, cabinet officers, and others popping up.
'All right,' said the president, 'let's have it.'
Lockwood nodded to an assistant and an image of the Deimos Machine flashed on the biggest screen at the end of the room.
'What you're looking at, Mr. President, is a photograph taken by the Mars Mapping Orbiter on March twenty- third of this year of an object hidden in a deep crater on Mars's moon, Deimos. Voltaire crater. Some background first: Mars has two tiny moons, Phobos and Deimos, named after the Greek gods of Dread and Terror. Both appear to be recently captured asteroids--recent as in half a billion years. Their almost perfectly circular orbits in the ecliptic have long puzzled astronomers, who've never been able to figure out how Mars could have captured these two asteroids into coincidentally perfect orbits unless a third body were involved, which removed some of the angular momentum from the other two and was flung away, never to be seen again. This has always seemed to astronomers to be a highly unlikely event.'
'What does this have to do with anything?'
'Mr. President, the idea has been raised that both Phobos and Deimos may have been placed in orbit artificially.'
'All right. Go on.'
Lockwood cleared his throat. 'The object you see in this picture--which we're calling the Deimos Machine--is clearly not natural. We believe it was built by an unknown, extraterrestrial intelligence. We believe it is the source of the gamma rays which the MMO has picked up. And we also believe it lobbed a lump of strange matter at the Earth on April fourteenth, and a larger piece at the Moon tonight, which as you know destroyed Tranquility Base. In this sense, it appears to be a weapon.
'A rough analysis of surface erosion from micrometeoroids and the accumulation of regolith around it indicates an age of between one hundred and two hundred million years old. All the satellites we have in orbit around Mars which can be redirected to Deimos are being redirected.
'Deimos is like a misshapen potato--it doesn't rotate like a normal planet. It sort of tumbles. Obviously the Deimos Machine can't fire unless Voltaire crater is oriented toward the Earth. And since it's a deep crater, the orientation has to be fairly close. That doesn't happen very often and not on a regular schedule.'
'And?'
'It was aligned in April, the night the strange particle struck. The next alignment was tonight. You saw what happened to the Moon.'
'When's the next alignment?'
'Three days from now.'
'When will the satellites be in position around Deimos?' asked the president.
'Over the next few weeks,' said Lockwood.
'Why so long?'
'Most require gravitational and orbital assists. They don't have the fuel to go jetting anywhere at a moment's notice.'
'Isn't it possible,' asked the president, 'that repositioning our satellites around Deimos might be seen as an aggressive maneuver?'
'The satellites are small, fragile, and clearly unarmed,' said Lockwood. 'But, yes, there's a danger that anything we do--anything--might be misinterpreted. We're dealing with alien thinking, even if it is alien A.I. It also might be defective. Malfunctioning.'
The DIA asked, 'This 'strange matter' that you say was fired at the Earth--I don't understand why it's so dangerous. Just what does it do?'
Lockwood spoke. 'It's a form of matter that converts regular matter into strange matter on contact, like Midas turning everything he touched to gold.'
'How would that be dangerous?'
'For one thing, the Earth would shrink to the size of a baseball. And then, because strange matter is unstable, it would explode with force so great it would blow apart the solar system, driving strange matter into the sun, which would then explode, affecting our corner of the galaxy.' His deep, pebbly voice seemed to echo ominously in the room.
'So why did the last one go
'It was very small and moving fast. It converted some matter, but that matter accreted onto it and all of it exited the Earth on the way out. That's why there wasn't a huge explosion of ejecta, magma, and so forth when it emerged. No shock wave developed. It was like a hot knife through butter, essentially. Our geologists tell us the vacuumed-out hole sealed up behind it. The Moon, on the other hand, was a much bigger chunk. It was too fast to convert the Moon, but it was big enough to generate a huge shock wave that rang the Moon like a bell and ejected a stream of debris.'
'So all this alien artifact has to do,' the DIA said, 'is lob another strangelet at the Earth and we're dead.'
'That's right. The key is speed. If it's tossed at us at a slow enough speed to be trapped inside the Earth, we're finished.'
A long silence settled in the room. 'Any other questions?'
