Quickly, the Keeper ushered Tinker Bell and the winter fairy through the vast hall. He pointed his cane toward a great room with a giant snowflake pattern on the floor.

The Keeper motioned for both fairies to stand in the center of the snowflake. “Your wings are safe in here,” he assured Tinker Bell.

Tink placed her coat on top of his cane and flew with the winter fairy to the middle of the snowflake. The Keeper tapped his cane on the floor, and the room went dark. Instantly, the snowflake Tink and the winter fairy were standing on lit up and rose off the ground. Amazed, the two fairies held perfectly still.

“Just put your wings into the light,” the Keeper instructed.

Together, the fairies lifted their wings into the sunlight streaming down from an opening in the ceiling. The rays shone through their wings. Then an incredible thing happened. The light began projecting images from their pasts on the icy chamber walls. The first picture was of Big Ben, the clock tower in London.

“The mainland,” Tinker Bell whispered, recognizing the landmark.

The scene switched to a baby laughing for the first time. The fairies watched as the laugh split in two and landed on a dandelion. Two wisps from the flower took flight and danced across a night sky. They floated past the Second Star to the Right and headed straight toward Never Land! But before they could reach the Pixie Dust Tree, one got caught on a branch. The other traveled on. A strong gust of wind came and blew the tangled wisp in the opposite direction, toward the Winter Woods.

“Oh, no,” Tink whispered.

Images of both fairies arriving in Pixie Hollow appeared—Tinker Bell in the warm seasons at the base of the Pixie Dust Tree, and the other fairy in the center of the Winter Woods.

“Two fairies born of the same laugh,” Tinker Bell said slowly. “So that means…”

“You’re my…” the winter fairy began.

“Sister,” they said at the same time.

The Keeper nodded and gestured to the fairies’ wings. “Yes, your wings are identical,” he said. “That’s why they sparkle.”

Turning their backs to each other, Tink and the winter fairy lined up their wings. The Keeper was right—the patterns matched perfectly! A bright spark of light suddenly burst forth when their wings touched. It created a beam that shone all the way up to the ceiling.

The two fairies jumped back. “Jingles!” they both cried. What was that?

“Ah,” the Keeper said. “Maybe you shouldn’t do that.”

Tink smiled. “I’m Tinker Bell,” she said happily.

“I’m Periwinkle,” her sister replied.

Tink thought back to how her wings had sparkled the first time she jumped into winter. “So, you must have been at the border?” she asked slowly.

Periwinkle nodded. “Yeah, I was hoping to see the animals cross.”

“I guess I didn’t see you,” Tink replied.

“Me either,” Periwinkle said, smiling. Then she looked down at the pom-poms on Tink’s boots. With an excited squeal, she reached into her pocket and pulled out two identical pom-poms. “I usually just wear them at home.” She grinned.

At that moment, a deep voice bellowed through the chamber. “Hello, Keeper. Are you in?”

“Yumpin’ yetis!” the Keeper exclaimed, startled. “Lord Milori!”

Periwinkle panicked. “If he sees you, he’ll send you back,” she said to Tinker Bell.

“Don’t a-worry,” the Keeper whispered. “I’m gonna take care of this.”

“Keeper?” Lord Milori called. “I need to speak with you. It’s important.”

Tink and Periwinkle crouched down on the large, hovering snowflake. As long as they stayed up there, Lord Milori wouldn’t be able to see them from down below.

“I’ll be right back,” the Keeper promised. Then he flew down to see Lord Milori.

“I’m right here,” the Keeper told the royal fairy.

“Did you receive the wing book?” Lord Milori asked.

“You know, once upon a time you’d stop by just to say hello and howdy-do,” the Keeper said, shaking his head. He pretended to look hurt.

Lord Milori sighed. “I’m sorry,” he replied sincerely. “Hello,” he added.

“Howdy-do,” the Keeper chirped.

“This book has me worried,” Lord Milori continued. “What if a warm fairy brought it here?”

The Keeper chuckled. “Well, that might be nice, then, meeting a warm fairy,” he said. “Especially one with such good taste in books.”

“It’s too cold,” Lord Milori said sternly.

“Well, maybe if they were wearing a coat or, you know, one of them little sweater vests,” the Keeper replied lightly. “They’re nice.”

The look that crossed Lord Milori’s face made it clear that he was losing his patience. “I’ll remind you, crossing the border is forbidden.”

“There was a time when it wasn’t,” the Keeper responded, growing serious.

“The rule is there to keep the fairies safe,” Lord Milori said. “That will never change. If a warm fairy comes here, you will send them back.”

He stared long and hard at the Keeper, and the elderly fairy dropped his gaze. “Of course,” the Keeper agreed softly.

Up above on the floating snowflake, Tinker Bell and Periwinkle exchanged a worried look. This didn’t sound good.

“Thank you,” Lord Milori said, turning to leave.

Once he was out of sight, the snowflake Tinker Bell and Periwinkle were on descended to the floor. The Keeper turned to Tinker Bell sadly. “Well,” he said, “you heard Lord Milori. You must go back home.” He paused and thought for a moment. “Of course, he didn’t say when,” he added with a twinkle in his eye.

The sisters hugged and cheered, happy to have more time to spend together.

“Now, listen, you two,” the Keeper told them. “It gets colder after dark, so it’s best to get Tinker Bell home before the first moonlight.”

Periwinkle gave the Keeper a big hug. “Thank you, Dewey,” she said.

Tinker Bell glanced at her sister, confused. “Dewey?” she asked. What did that mean?

“That’s his real name,” Periwinkle explained.

“It’s what my friends call me,” said the Keeper.

A big smile spread across Tinker Bell’s face. “Thank you, Dewey,” she said happily.
