The Mystery of the Missing Storybook

"I wonder how books are made?" David pondered aloud, gazing at the shelf full of colorful spines in his room. His furry lizard, Jacob, blinked slowly from his perch on the windowsill, seemingly deep in thought too. A mischievous glint danced in David’s eye. “Come on, Jacob! Let’s go find out!”

Suddenly, the bookshelf shimmered. A moment later, a glowing doorway appeared, swirling with colors like a rainbow lollipop. "Whoa!" exclaimed David. Jacob, usually a fan of naps, sprang to his feet, his little tongue flicking excitedly. "Adventure time!" chirped David, rushing towards the shimmering portal, Jacob hot on his tail.

The doorway deposited them in a bustling courtyard filled with cobblestone paths and whimsical fountains. A magnificent castle, crafted from sparkling stones of every color imaginable, soared above them. "Wow! This is even cooler than Dino Land!" David gasped, his eyes wide with wonder.

A sign shimmered above a drawbridge leading into the castle courtyard. It read: “Welcome to the Enchanted Castle!” David and Jacob, their curiosity piqued, scurried across the drawbridge.

Inside, they stumbled upon a group of children huddled around a teary-eyed woman with a pointed hat. A kindly witch! "What's wrong?" David asked, his explorer instincts kicking in.

“Oh, dear travelers,” the witch sighed, dabbing at her eyes with a lacy handkerchief. “Someone has stolen my most prized possession – the Book of Untold Tales! Without it, no new stories can be written, no new adventures can be had! Imagine, no more bedtime stories!”

David gasped. He couldn't imagine a world without stories! “We'll help you find it!” he declared. Jacob puffed out his chest and nodded in agreement.

The witch beamed, “Thank you, young adventurers! Here are three clues. Use them wisely, and you might just find the missing book."

She handed David a small scroll. He unfurled it carefully. The first clue was a riddle: "I am a place where words come alive, but I have no voice of my own. What am I?"
