The Hill That Hums

The Quantum Quest Science Museum sat at the very top of a steep, windy hill, shaped like a colossal glowing atom — three silver rings looping around a bright white dome. At night, it pulsed like something alive.

Penelope Starwrite arrived just after opening time, her rainbow cloak snapping in the morning breeze. She had her sketchbook tucked under one arm and a pen behind each ear.

Inside, the space exhibit was her favorite — planets hanging on invisible wire, a floor painted like a star map, and walls that shimmered faintly in the low light. She'd been here four times already. This visit, she planned to draw the whole solar system from memory.

She pressed her pen to a fresh white page and exhaled slowly.

"Not bad," said a voice beside her. "For a warm-up sketch."

Penelope looked up. A girl stood there, arms crossed, smiling like she already knew something Penelope didn't.

The Girl with the Navy Jacket

The girl dropped her arms and stuck out a hand.

"I'm Zara," she said. "And that's Saturn, by the way. You gave it too many rings."

Penelope looked down at her sketch. Saturn had exactly seven rings. She'd counted.

"It has seven," Penelope said.

"Mine has the right amount." Zara flipped open her own sketchbook. Hers had seven rings too, but they were thinner, more precise, drawn with a technical pen that clearly cost more than Penelope's.

"That's the same number," Penelope said flatly.

Zara smiled. "Mine look better."

Before Penelope could answer, a low mechanical hum filled the room. A small boxy drone — the kind museum staff used to adjust the hanging planet models — drifted down from the ceiling. It was carrying a folded paper card.

The drone dropped the card between them and buzzed back up.

Penelope unfolded it. The message inside was printed in bold letters:

DRAWING COMPETITION. SPACE EXHIBIT. RIGHT NOW. FIRST DRAWING TO TOUCH THE CEILING WINS.

Below that, in smaller letters: The ceiling is forty feet up. You have five minutes.

Zara had already uncapped her pen.
