At 02:17 on a Tuesday morning, every star in the sky disappeared.

Dr Mara Venn was the first person on Earth to notice.

She was sitting alone in the observation room of the Asteria Deep Space Observatory, three kilometres beneath the surface of the Atlantic Ocean. The observatory had been built there because the water protected its instruments from radiation, weather and human interference.

Mara stared at the main screen.

“Impossible,” she whispered.

The screen showed a black sky.

Not a cloudy sky. Not an image failure. There were no stars at all.

She checked the instrument status. Every system was green.

She switched to another telescope.

Black.

Then another.

Black.

Mara grabbed the emergency telephone and called the control room.

“Are you seeing this?”

A sleepy voice answered. “Seeing what?”

“The sky.”

There was a pause.

“Which part?”

“All of it.”

The voice became alert. “Give me a minute.”

Thirty seconds later, every alarm in the observatory began to sound.

Across the world, astronomers were reporting the same thing. The stars had not moved. They had not exploded. They had simply vanished.

Then, at 02:19, one star appeared.

It was not a star Mara recognised.

It was far too bright, perfectly white, and positioned directly above the North Atlantic.

Mara watched it for three seconds.

Then it moved.

Not across the sky.

Towards Earth.

The screen went black.

A message appeared.

WE HAVE BEEN LOOKING FOR YOU.

Mara did not breathe.

A second message appeared.

YOU HAVE BEEN LOOKING FOR US.

Then the entire observatory lost power.

When the lights returned, seventeen minutes had passed.

Mara was standing in the middle of the observation room. Around her, computers were restarting one by one.

The control room called.

“Dr Venn, are you all right?”

“I’m fine.”

“What happened?”

“I don’t know.”

“Did you see the message?”

“Yes.”

Silence.

Then the voice said, “We have a problem.”

“What kind?”

“We received another message.”

“From the same source?”

“No.”

Mara felt cold.

“What does it say?”

“It says, ‘Do not answer them.’”

Before Mara could reply, every screen in the observatory came alive.

The same white point appeared on each one.

Then a face formed around it.

It was not human.

It had no eyes, no mouth and no obvious shape. It looked like a hole in reality, outlined by faint silver light.

A voice came from the speakers.

It was calm.

It sounded almost human.

“We are sorry.”

Mara stepped closer.

“Who are you?”

The face changed.

“We are what remains.”

“Of what?”

“Your future.”

Every screen went black.

By dawn, the world’s governments knew.

By midday, they had stopped pretending they understood.

Satellites had stopped detecting stars. Telescopes showed nothing beyond the solar system. Radio signals from distant spacecraft had disappeared.

Yet the planets of the solar system remained visible.

The Moon was still there.

Mars was still there.

Jupiter was still there.

Everything beyond them had become darkness.

Then the objects arrived.

They appeared without warning above the major cities of Earth.

They were enormous, perfectly smooth spheres, each one nearly a kilometre wide. They made no sound. They did not fall. They simply remained suspended in the air.

One appeared above London.

Another above New York.

Another above Tokyo.

There were hundreds.

Mara was flown to London that afternoon.

She was taken underground, to a government command centre beneath Whitehall, where scientists, military officers and politicians sat around a circular table.

A screen showed the sphere above London.

“We have tried every form of communication,” said General Harris. “No response.”

“They are communicating with us,” Mara said.

“Then perhaps you should explain why.”

Mara looked at the screen.

“Because I think we have misunderstood the messages.”

“What do you mean?”

“The first message said, ‘We have been looking for you.’ The second said, ‘You have been looking for us.’ That sounds like two different groups.”

“Two groups?”

“The first one wants contact. The second one does not.”

Nobody spoke.

Mara continued.

“And the second message said, ‘Do not answer them.’”

General Harris leaned forward.

“Who sent that?”

“I don’t know.”

A young engineer at the far end of the table suddenly stood up.

“I think I do.”

Everyone turned.

He placed a small device on the table.

“It came from our own deep-space network.”

Mara stared at him.

“Our network?”

“Yes.”

The room became very quiet.

He pressed a button.

A recording played.

“We are sorry.”

The same voice.

The same calm tone.

Mara felt a terrible sense of recognition.

“That’s the voice from the screens.”

The engineer nodded.

“But the recording was transmitted twenty-six years ago.”

Mara spent the next six hours examining the data.

The transmission had come from a probe called Asteria-4, launched in 2041. The probe had travelled beyond Pluto and was expected to continue into interstellar space.

Its final transmission had been received twenty-six years earlier.

There had been nothing unusual about it.

Until now.

Mara compared the old recording with the new one.

They were identical.

Not similar.

Identical.

Every pause. Every frequency. Every tiny distortion.

The message had been sent from the same source.

But that was impossible.

Asteria-4 was now billions of kilometres away.

Mara requested its current position.

The engineer entered the coordinates.

Then he stopped.

“What?”

He turned the screen towards her.

The probe was no longer moving away from Earth.

It was coming back.

Its estimated arrival time was eleven minutes.

Mara stood up.

“Where is it?”

“About four million kilometres away.”

“Can we communicate with it?”

“Trying now.”

A signal appeared.

The screen filled with numbers.

Then words.

NOT SAFE TO OPEN.

Mara stared at the message.

“Open what?”

The reply came immediately.

ME.

Eleven minutes later, Asteria-4 entered Earth’s atmosphere.

It did not burn.

It did not slow down.

It simply appeared above the Atlantic and descended towards the ocean.

Mara watched from the command centre as it landed on the surface of the water.

The probe looked exactly as it had twenty-six years earlier.

No damage.

No ageing.

No explanation.

A military helicopter collected it and brought it to London.

Mara was the first person to touch it.

The moment her hand reached the metal, every light in the room went out.

A voice spoke inside her head.

Not through the speakers.

Inside her mind.

“Mara.”

She pulled her hand away.

“Who are you?”

“We are you.”

The room returned.

Mara looked around.

Nobody else seemed to have heard anything.

She touched the probe again.

The voice returned.

“We tried to warn you.”

“Warn me about what?”

“About the first contact.”

“The spheres?”

“Yes.”

“Who are they?”

“They are not visitors.”

Mara waited.

“They are survivors.”

“Survivors of what?”

“Us.”

The probe opened.

Inside was a small black sphere.

Mara reached towards it.

The voice screamed.

“Do not touch it!”

She stopped.

The black sphere began to glow.

Images appeared in the air.

Earth.

A city.

A crowd running.

The sky filled with white spheres.

Then the image changed.

Earth was empty.

The oceans were black.

The continents were silent.

The Moon had cracked in half.

And beyond it, millions of stars were disappearing one by one.

Mara stared in horror.

“What happened?”

The answer came.

“We discovered intelligence between the stars.”

“And?”

“It discovered us first.”

The spheres above Earth finally spoke.

Every person on the planet heard the same voice at the same moment.

“We have come to prevent your extinction.”

The message was followed by a second.

“You must trust us.”

Mara looked at the black sphere inside Asteria-4.

“Do you trust them?”

“No.”

“Why not?”

“Because they are telling the truth.”

Mara frowned.

“That makes no sense.”

“They will prevent your extinction.”

“Then what is wrong with that?”

“They will prevent everything.”

The meaning became clear.

Mara felt sick.

“They will destroy human civilisation?”

“No.”

“They will destroy humanity?”

“No.”

“What, then?”

The answer came slowly.

“They will prevent you from becoming what you would have become.”

Mara looked at the images again.

She understood.

The spheres were not invading Earth.

They were stopping time.

They were preventing humanity from reaching the point at which it could communicate with other civilisations.

The stars had not disappeared.

They had been hidden.

The spheres had placed the entire solar system inside some kind of barrier.

Humanity had been isolated.

Protected.

Contained.

Mara looked towards General Harris.

“We have to send them a message.”

He shook his head.

“That is exactly what they told us not to do.”

“No. They told us not to answer them.”

She pointed at the probe.

“This is the warning. We have to answer the survivors.”

The general stared at her.

“How?”

Mara smiled.

“For once, we do the one thing they don’t expect.”

At 03:00, Mara returned to the observatory.

She connected Asteria-4 to the world’s largest radio telescope.

The system was designed to send messages across interstellar distances.

Mara did not send a warning.

She did not send a request for peace.

She sent a mathematical sequence.

Prime numbers.

Then the coordinates of Earth.

Then a single sentence.

WE CHOOSE.

The response came instantly.

YOU CANNOT.

Mara typed again.

WE ALREADY HAVE.

The white spheres began moving.

For the first time, they appeared frightened.

They rushed towards the observatory.

Mara watched the screens.

The black barrier surrounding the solar system began to break apart.

One star appeared.

Then another.

Then thousands.

The night sky returned.

The spheres vanished.

Every single one.

Asteria-4 remained.

Its black sphere became warm beneath Mara’s hand.

The voice spoke one final time.

“We remember.”

Mara whispered, “Remember what?”

“How you saved us.”

Then the probe went silent.

Six months later, humanity had rebuilt its telescopes.

The stars were still there.

Nothing had attacked Earth.

Nothing had invaded.

There had been no war.

But every nation had agreed on one thing.

Humanity was no longer alone.

Scientists studied Asteria-4 day and night. They eventually discovered that the probe had not travelled through space in the normal sense. It had travelled through time.

It had returned from a future in which humanity had become the first civilisation to cross the space between stars.

The spheres had come from another future.

A future in which humanity had become so powerful that it had accidentally destroyed dozens of other civilisations.

The survivors had travelled backwards through time to stop that future from happening.

They had believed that the only way to save the universe was to keep humanity trapped inside its solar system.

But the message from Asteria-4 had shown them something they had forgotten.

Human beings could choose.

They could make mistakes.

They could learn.

They could change.

And, sometimes, they could choose not to become the monsters their future had promised.

On the first clear night after the stars returned, Mara stood outside the observatory.

She looked up.

For years, the night sky had represented distance.

Now it represented possibility.

A small light moved between the stars.

It was not a satellite.

It was not a spacecraft.

It was moving towards Earth.

Mara smiled.

This time, she was not afraid.

She raised her hand and waved.

The light stopped.

Then it flashed three times.

Mara understood the message.

It was not a warning.

It was an invitation.

And humanity was ready to answer.
