The heat was the first thing you noticed when you came to the town. It wasn't just hot, it was thick, a wet blanket that pressed down on your shoulders and wouldn't let go. The mosquitoes were the second thing. They came in clouds, singing their high, thin song as they descended.

Calina LeBlanc was twenty-six, the owner of the town's only radio station, and the last descendant of the LeBlanc plantation that had once covered half the county. The plantation was gone now, swallowed by time and neglect and the slow, patient rot of the Mississippi delta. All that remained was the radio station, a small brick building on the edge of town with a rusted antenna that reached for the sky like a broken finger.

She was also the keeper of secrets. The LeBlanc family had secrets, deep dark things that had been buried in the soil and the blood and the silence of generations. Calina knew them all, and she kept them all, like a gardener tending poisonous flowers.

The war had come to the town three weeks ago. Not a real war, not with battles and uniforms and flags. A cold war, a shadow war, a war of codes and signals and secret messages that nobody in the town understood but everybody felt in their bones.

The radio station was the only place where the signals still came through clear. Everything else was being jammed, intercepted, broken. The enemy's code machines were eating through communications like termites through wood.

Calina sat at the radio transmitter, her fingers on the microphone, listening to the static. It was a lonely sound, the sound of a world falling apart.

The door opened and a man walked in. He was tall, pale, with golden hair and eyes that seemed to look through her rather than at her. He wore a linen suit that had seen better decades and carried himself like a man who was used to being ignored.

"Miss LeBlanc?" he said.

"Cal. Who are you?"

"Mike Thibodeaux. I'm a... distant relative. And I've been sent to help with the signal problem."

She knew the name. Everyone in the town knew the name. Mike Thibodeaux was the family madman, the genius who had been locked away in the asylum for years. He was also, everyone whispered, cursed.

"What signal problem?" she asked.

"The one that will save us." He set his satchel on her desk and opened it. Inside were charts, equations, photographs of the sun. "We're going to adjust the antenna frequency. The right frequency will trigger a solar radiation burst, which will send an electromagnetic pulse across the entire delta. Every radio, every code machine, every communication system in the enemy's army will be blinded."

Calina stared at him. "You're going to set the sun on fire?"

"I'm going to tickle it. A small perturbation, precisely calculated, will set off a chain reaction. The sun is a delicate balance, Cal. A grain of sand in the eye."

"And what happens to you?"

Mike smiled, and for the first time she saw something human in his pale face. "I'll be at the tower. At the top. When the antennas are aligned, the radiation will... well." He trailed off. "It's the only way to calibrate the final adjustment. Someone has to be there."

Calina felt a coldness spread through her chest. "You'll die."

"I'll do something useful for once." He closed his satchel. "Are you with me or not?"

She looked at the silent radio transmitter, at the rusted antenna reaching for the sky, at the heat pressing down on the town. She thought of her family, dead and forgotten, their secrets buried in the soil. She thought of the LeBlanc curse, the madness that had haunted her family for generations.

"When do we start?"

They worked through the night. Mike's equations were beautiful, precise, almost musical. He spoke of the sun the way a priest might speak of God, with a reverence that bordered on madness. Calina listened, her fingers tracing the equations, trying to understand the logic beneath the poetry.

By dawn they had calculated the frequency. By noon they had repaired the antenna array on the tower. By evening they were waiting for the enemy to come.

The enemy was closer than they thought. Judge Parker's men had been tracking them for days, and now they were closing in, riding through the swamp in armored trucks that chugged like dying animals.

"Cal," Mike said. "I need you to send a message. Anything. Just... send something."

She sat at the radio transmitter, her fingers on the microphone. Below them, the town was disappearing into the heat haze. The mosquitoes were singing their high, thin song.

Mike climbed the tower, his linen suit billowing in the hot wind. He adjusted the final antenna, his hands steady despite the heat, despite the danger, despite the fact that he was about to die.

"Ready," he said.

Calina pressed the microphone. "This is Calina LeBlanc, broadcasting from the only radio station in a town that doesn't exist anymore. Good evening, mes amis. It's midnight, and the world is ending, but we're still playing jazz."

Mike stood at the top of the tower, his arms outstretched, his face turned toward the sun. The electromagnetic burst hit like a wave, and the antennas glowed blue in the heat haze.

Then he was burning.

Calina screamed, but the sound was swallowed by the heat. She kept speaking, kept broadcasting, kept sending message after message into the silence, tears streaming down her face, blood on her fingers from where the metal had cut her.

The electromagnetic pulse hit at midnight. Every radio in the delta went silent. Every code machine died. Every communication system in the enemy's army blinked out like a candle in the wind.

The delta had returned to the age before Marconi.

In the morning, Calina found Mike's pocket watch on the tower floor. Inside the case was a photograph of a man and a boy standing in front of a telescope, both of them smiling at something the photographer couldn't see.

She sat on the steps of the radio station and tapped out a message on her radio key. No one was listening. No one would ever listen again. She was just tapping her heartbeat, the rhythm of a heart that was still beating in a world that had gone forever silent.

The heat lifted slightly, revealing a sky the color of rust. Calina didn't look up. She kept tapping, keeping time with something only she could hear.
