When Antek and Kalina see a strange green flash fall beyond the city, a bike ride to the forest leads them to a scorched clearing and a machine that should not be there.
Among the grey apartment blocks on the Sunnyside estate, summer usually began with the noise of scooters, open windows, and shouting from the courtyards below. This year, Antek and Kalina had a better plan. They climbed to the roof with a telescope, a flask of tea, and a blanket, because their dad had said the sky might fill with meteors after dark.
Antek loved anything that blinked, burned, or broke the rules of normal life. Kalina liked rules just enough to spot when something ignored them. They were still arguing about which constellations were easiest to find when the sky suddenly split open.
A green flash streaked overhead, so bright it washed the rooftops in daylight. It moved too slowly to be a meteor and too smoothly to be anything they knew. For one impossible second, it seemed to hang above the forest beyond the city limits, glowing like a wound in the dark. Then the light vanished. The estate went black again, as if someone had shut a door on the universe.
Kalina checked her watch. Only two minutes had passed.
Antek was already on his feet. “We have to go there,” he said, hardly able to keep his voice steady. “That wasn’t normal.”
The next afternoon, as soon as their online lessons ended, they pedalled hard towards the forest. The path grew quieter the farther they went. Even the sunlight seemed different under the trees, as if a pale green shimmer had settled over the leaves.
In a small clearing, they found a circle of grass scorched cleanly away. At its centre stood a metallic object, half-buried in the earth, its surface covered in thin lines that pulsed faintly, like a heartbeat under steel.
Antek slowed his bike. Kalina forgot to breathe.
A sound drifted from the object then, so soft it might have been a whisper. The metal shivered. A seam slid open.
Inside, something deeper in the machine lit up with a hard green glow, and from behind them came a crack of snapped branches.
