Mirror Lake was as clear as blue quartz in the early morning sun. Tiny sailed past the Little Laughter Library in her paper-boat then stopped to wave at her reflection. There were two of everything: two pencil-sized girls, two paper-boats, and two Little Laughter Libraries with shiny copper roofs. The world felt rich and full. In an instant, a sunbeam flashed through the pines, catching Tiny off guard. She toppled into the water with a splash! Down she tumbled, past cattails, weeds, and curious minnows—straight into an open door which snapped shut behind her.

Tiny stood up and looked around. She was in the Little Laughter Library! At first it seemed identical to the library above, but everything was different. Instead of the brightly painted walls and shelves packed with puns, the room was gloomy and the racks were bare. Through the round window where the sun usually glimmered hovered a circle of dark smoke.
“Hello, Tiny. Welcome to the Underland,” it said in a deep, gravelly voice. “I am Moonshadow.”
Tiny’s heart raced. “The Underland? You mean we’re. . .”
“In the Below, yes,” Moonshadow interrupted. “A mirror to Above. Except that dawn never breaks and the sun never shines. Excuse my rudeness, we don’t get many visitors.” Moonshadow’s cheeks darkened.
Tiny watched the shadows creeping closer and shivered. “But it’s so grey and dingy. Shall I bring down a sunbeam? It might brighten the place up.”
No!” Moonshadow rumbled. “It would surely upset the natural balance. We need to find a way to illuminate our world—without light.”
“Hmm, that sounds tricky.” Tiny scrunched her brow as she searched for a solution. “I’ve got it!” She stabbed the air with her finger. “I could tell you a story!”
“That might just work!” Moonshadow said with a hopeful smile.

And so Tiny told a story of toasting marshmallows by the campfire, of giggles with friends among the wildflowers, and of the majesty of stars on a clear, cloudless night. Tiny’s heart felt like it was on fire. The air in the room was clearer, brighter.
“I think you did it,” Moonshadow sniffed, his smoky eyes glistening. “You’ve illuminated our world. Thank you. You’d better be getting along, the Overland needs you.”
Tiny nodded and took Moonshadow’s hand. With a sudden swoosh she was torpedoed through the water until she burst back through the surface. Tiny clambered back onto the paper-boat, watched the light-sparkles dance on the water, and blew Moonshadow a silent kiss. The world was richer than ever.
