Olek and Lena uncover a hidden passage behind their grandfather's old clock and are swept into a strange place where time no longer behaves as it should.
Olek always dreaded summer visits to Grandfather Kazik's house. The old place at the edge of the village creaked in the wind, the floors sighed under every step, and dust clung to the corners like old cobwebs. The only thing that ever caught his eye was the tall wooden clock in the living room, with its carved birds and dark, polished door.
This summer, though, Lena was with him. His cousin never ran out of ideas, and she looked at the world as if every drawer, attic, and locked box was hiding a secret.
When rain rattled against the windows one afternoon and they had already played every game they could think of, Lena crossed the room and pressed her ear to the clock.
"Something's humming," she whispered. "Do you hear it?"
Olek frowned. "It's probably just the house. Or mice."
Lena didn't move away. Her fingers traced the carved wood, slow and careful, until one of the panels gave a soft click.
Olek jumped back. A narrow seam opened in the side of the clock, and a small door slid free as if it had been waiting for years to be found.
Darkness breathed out from inside.
Lena grinned. "We're going in."
Before Olek could argue, she slipped through the opening. He swallowed hard and followed her into a tight tunnel that smelled of dust, cold metal, and something sharp and unfamiliar, like thunder before it breaks. The passage twisted once, then opened into a round chamber lit by a pale, trembling glow.
In the middle of the room stood an old golden hourglass, suspended in the air as if held by nothing at all.
Lena reached toward it. "It's beautiful."
The moment her fingers touched the glass, the sand inside began to race downward. Faster. Faster. The light around them flared white, then gold, then deep blue, and the floor lurched beneath Olek's feet as if the whole room had been yanked loose.
A heartbeat later, everything went still.
Olek and Lena were standing in the middle of a place neither of them knew. Narrow streets spread out around them, lined with strange houses and wooden stalls. People in unfamiliar clothes hurried past, carrying baskets and bundles. The air smelled of fresh bread, smoke, and rain on stone.
"Where are we?" Olek whispered.
Lena didn't answer.
A boy about their age had stepped into the street and was staring at them with wide eyes. He wore a rough linen shirt and had a wooden sword tied at his side, but it was the look on his face that made Olek go cold.
The boy pointed at them and shouted, "You! Who are you?"
