On the last trip before graduation, four friends stay by a lonely lake, where old tensions and a storm reveal something impossible on the island.
Lake Andromeda lay still under the summer heat, a dark sheet of water ringed by forest so thick it seemed to press the shore inward. In the middle of it sat a small island, and on the island stood the broken shell of an old observatory, its dome half-collapsed and black against the trees. It looked abandoned from a distance. Up close, it never quite felt that way.
This was the last trip Lena, Krzysiek, Maja and Igi would ever take together before high school ended, and none of them said that out loud. They did not need to. It hung between them anyway, along with all the things they had left unsaid for weeks: the arguments that had gone nowhere, the jokes that landed too sharply, the silences that lasted too long.
Their wooden cottage crouched at the edge of the forest like it had been built to listen. Inside, the air smelled of pine, damp floorboards and lake water brought in on their clothes. Lena sat by the open window with her notebook on her knees, pretending to write while she watched the light shift over the lake. Igi kept trying to break the tension with stupid remarks, but even his grin looked tired around the edges.
Krzysiek was the worst at hiding things. He stood on the porch more than he sat inside, staring across the water as if he expected it to answer him. Maja, restless as ever, kept disappearing outside and coming back with wet grass on her ankles and a new plan every five minutes. She seemed to be moving faster than the rest of them, as if standing still would give the evening time to catch up.
By sunset, the sky had turned the colour of old metal. Clouds rolled in low over the lake, and the air changed so quickly that Lena felt it in her teeth. Then the first thunder broke somewhere beyond the trees, and rain followed hard and sudden, drumming on the roof and blurring the shoreline into grey streaks.
They were gathering on the narrow wooden platform near the water when Maja froze.
At first Lena thought she had been startled by lightning. Then she saw where Maja was looking.
On the island, between two jagged sections of the observatory wall, a figure stood motionless in the rain.
No one spoke. Another flash lit the lake white, and for a second the shape was clearer than it should have been: human, upright, watching them. When the darkness came back, the island seemed farther away than ever, and somehow closer too, as if the water between them had thinned.
Igi let out a short laugh that did not sound like a laugh at all.
"Tell me that was a branch," he said.
Nobody answered.
Lena felt the old knot in her chest tighten. It was not just the figure. It was the timing, the way the night had arrived with all its weight, as if it had been waiting for them to notice. Weeks of almosts and maybes flickered through her mind: the thing Krzysiek had nearly said, the message Maja had deleted, the way Igi kept looking away whenever anyone mentioned leaving.
Maja took one step closer to the edge of the platform, rain plastering her hair to her face.
"Someone's there," she whispered.
Krzysiek finally turned from the lake. For once, he did not try to sound calm.
"I need to tell you something," he said, and stopped as another flash of lightning tore across the water.
The figure on the island was gone.
For one breath, the storm seemed to hold still. Then Lena saw movement near the boat tied below the platform. Not a person this time. Something darker. Thinner. A shadow sliding along the side of the hull as if it had a life of its own.
Maja reached for the railing.
"Do you see that?" she said.
No one dared answer her.
