It was a windy afternoon. Orange and yellow leaves were flying everywhere, like crazy butterflies. Alex, Violet, Ella, and Larry were building a fort with blankets in Alex's living room. They had taken all the sofa cushions and put them under a big blue sheet.

"This is our secret house!" said Alex, hopping happily as he always did.

"I want to be near the entrance," said Violet in a decisive voice, arranging her little corner with her blue eyes sparkling.

Ella had already curled up in a soft corner, while Larry ran to get more cushions.

Sophie, Alex's black kitten, came into the fort and curled up on Ella's legs. Dora, the brave tabby cat, stood guard outside. Chubby, the big fat cat, slept near the sofa, and Max, his more agile brother, watched everything from the top of the bookshelf.

Outside the window, the wind was blowing harder and harder. And right at that moment, everyone heard a sound they knew well.

"CHUFF CHUFF!"

"Toby!" shouted Alex, running out of the fort.

And indeed, right in the middle of the living room, Toby the Magic Train appeared. He was small, painted red and gold, with a smiling little face painted on the front. From his little chimneys came smoke that smelled like candy.

Toby the Magic Train whistled and said in his cheerful little voice:

"Hello children, are you ready to go? Among books and stories I want to take you! A special place where everything is written, and a bearded friend awaits your arrival!"

"Where are we going?" asked Larry, curious.

But Toby the Magic Train didn't answer. He whistled again and opened his little doors.

The four children climbed aboard. Alex's four cats also jumped inside: Sophie sat on Alex's lap, Dora near the window to look out, Chubby lay down on the carriage floor, and Max climbed onto the highest seat.

"CHUFF CHUFF!"

The little train departed, and everything became magical. They went out through the window, flew over the houses, over the trees, over the clouds. The sky was gray, but suddenly they saw something incredible: a double rainbow! Two rainbows together in the sky, one big and one smaller.

"How beautiful!" exclaimed Ella, who usually spoke little, but this time was too excited to stay quiet.

The little train passed through the rainbows, and when it came out the other side, the children found themselves in front of an enormous building. It was a library, but not a normal library. It was as tall as a castle, made of honey-colored bricks, with huge windows. On the windows there were raindrops sliding down, as if they were racing each other.

"Look at the drops!" said Violet. "That one is winning!"

Toby the Magic Train stopped in front of a large wooden door. The children got off, and the cats followed them.

They entered the library. Inside there were very tall shelves that reached up to the ceiling. Books of all colors: red, blue, green, yellow, purple. Some books had covers that sparkled, others looked very old. There was a strange scent, of old paper and vanilla, like grandma's cookies.

"Ohhhh," whispered Alex, looking around with his mouth open.

In the middle of the library, sitting on an enormous armchair made of woven paper pages, was an old gentleman. He had a very long white beard that reached down to his belly. He wore a blue pointed hat with golden stars, and a purple robe.

A wizard! A wizard is a person who can do magic, that is, impossible things that seem like incredible tricks.

The wizard stood up slowly, leaning on a staff made of polished wood. He walked calmly, stroking his beard.

"Welcome, little visitors," said the wizard in a kind but sad voice. "I am Wizard Bookwell, the guardian of this library."

"Guardian?" asked Larry, scratching his head. "What's a guardian?"

The wizard smiled. "Good question, little one! A guardian is someone who protects and takes care of something important. I take care of all these books."

"Like a dad who takes care of children?" asked Violet.

"Exactly!" said Wizard Bookwell.

But then his smile disappeared. His eyes became shiny, as if he wanted to cry.

"Unfortunately," said the wizard, "something terrible has happened."

He pointed to a large book open on a table in the center of the room. It was a beautiful book, with a golden cover and drawings of fairies and dragons. But inside... it was empty! There wasn't even one page.

"This is the Book of Fairy Tales," explained Wizard Bookwell. "The most important book in the whole library. It contains all the stories in the world. But this morning, when I opened it, all the pages had flown away!"

"Flown away?" said Alex, with wide eyes.

"Yes," said the wizard sadly. "The pages of this book are magical. They can fly like birds. But something scared them, and they escaped. If they don't return to the book before sunset, all the fairy tales in the world will disappear forever!"

Ella hugged close to Violet. Larry stopped running. Even the cats seemed worried: Dora growled softly, Sophie hid behind Alex.

"We'll help you!" said Alex, jumping forward.

But right as he spoke, something fell from his pocket. A page. An old page, with drawings of a dragon and a princess.

Everyone looked at the page on the floor. Then they looked at Alex.

Alex's heart began to beat very fast. He remembered. That morning, before the little train arrived, he had found that page on the windowsill. It had seemed so beautiful that he had put it in his pocket, without thinking too much about it.

"Alex," said Violet, crossing her arms. "Is that a page from the book?"

Alex felt his face getting hot. He was scared. Scared that the wizard would get angry. Scared that his friends would think he was bad.

Wizard Bookwell approached slowly. He didn't seem angry, but he was waiting.

Alex looked at his friends. He looked at his cats. Sophie purred at him, as if to say: "Be brave, Alex."

Alex took a big breath.

"I... I took it," he said quietly. "I found it and put it in my pocket. I didn't know it was important. I'm sorry."

He told the truth. Even though he was scared.

For a moment, no one spoke. The silence was heavy.

Then Wizard Bookwell did something incredible. He smiled. A huge smile that lit up his whole face.

"Well done, little Alex," said the wizard. "You told the truth. Do you know what that means?"

"That I was honest?" asked Alex, with a trembling voice.

"Exactly! Honesty is a beautiful thing. It means telling the truth even when it's difficult. And you know what? The pages of the book only come back when someone tells the truth!"

At that moment, something magical happened. The page that had fallen from Alex's pocket began to glow. Then, out of nowhere, other pages appeared! They flew from behind the shelves, from under the tables, from above the lamps. Dozens and dozens of glowing pages!

"They're coming back!" shouted Larry, jumping with joy.

The pages flew toward the empty book, and one after another, they settled into their place. It was like watching a puzzle that completed itself.

But then, some pages stopped in mid-air. They couldn't go forward.

"Oh no," said Wizard Bookwell. "The magic isn't complete yet. More truth is needed!"

Violet looked at the floor. "I... once I said I had finished my soup, but I had hidden it under the napkin."

A page lit up and flew into the book.

Ella spoke softly: "I said the torn drawing was done by the cat, but it was me."

More pages flew.

Larry hopped: "I said I hadn't eaten the cookies, but I still had crumbs on my shirt!"

Even more pages returned to their place!

Every truth made more pages come back. The children laughed and hugged each other. Alex's cats all purred together.

Finally, the last page flew into the book. It closed with a soft sound, like a happy sigh. On the cover appeared golden writing that wasn't there before: "Thanks to the honest children."

Wizard Bookwell clapped his hands. "You did it! You saved all the fairy tales in the world!"

"Hooray!" the children shouted together.

The wizard opened a drawer and pulled out four little magical bookmarks. Each one had a little star that sparkled.

"These are for you," he said. "Every time you tell the truth, the little star will shine. This way you'll always remember that being honest is the most beautiful thing."

The children took their bookmarks carefully.

Outside the library window, the sun was setting. Orange and pink colors painted the sky.

"It's time to go home," said Alex.

They said goodbye to Wizard Bookwell with big hugs. The wizard, wise like a grandfather, walked them to the door.

"Come back whenever you want," he said. "The books will always be waiting for you."

Toby the Magic Train was waiting outside, puffing quietly.

"CHUFF CHUFF!"

The children climbed aboard with their cats. Toby the Magic Train whistled and said:

"The truth you've learned to say, and the fairy tales you've brought back today! Honest children, brave and true, go home like knights, all of you!"

The little train departed, crossed the rainbows again, flew over the clouds, and in an instant they were back in Alex's living room.

The blanket fort was still there. The wind outside had calmed down.

"What an adventure!" said Violet.

"I'm a little tired," said Ella, and she curled up on a cushion.

Alex looked at his bookmark. The little star glowed faintly.

"You know what?" he said. "Telling the truth was hard. But afterward I felt better."

Larry nodded. "Me too! It's like when you take off tight shoes."

Everyone laughed.

And do you know the important thing that Alex, Violet, Ella, and Larry learned?

Being honest is like wearing the most beautiful outfit in the world. At first it may seem difficult to tell the truth, especially when we're afraid of being scolded. But when we tell the truth, we feel light and happy inside. And others trust us. Honesty is a gift we give to ourselves and to those who love us.
