A photograph with one extra girl. A missing medal. A clock stopped at 6:20.

For forty years, the most important photograph in the Museum of Little Stories showed ten children.

But that morning... there were eleven.

Who had been left out of the story?

Luna is eight years old. She has a notebook for recording her discoveries and a special talent for spotting details that others miss. But to solve this case, she will have to learn something very important: a true investigator doesn't rush to guess. First she observes, then she asks questions, and only then does she decide.

And this investigation won't be complete without one new member:

The reader.

The Mystery I Solved at Age 8 is an interactive adventure in which every girl can read, observe, choose, write, connect clues, and build her own explanation of the mystery.

Across eight exciting missions, she will explore the Library of Whispers, the Courtyard of Footprints, the Workshop of Unfinished Inventions, the Market of Bells, the Garden of Changing Paths, the Station of the Three Platforms, and the mysterious Clockmaker's Tower.

At each location, she will discover photographs, symbols, schedules, objects, and eyewitness accounts that she must examine carefully.

Inside, she'll find:

• A Practical Guide explaining how to use the book.
• An Investigator's Promise to complete with her own name.
• A Clue Notebook for drawing and recording clues, facts, and new questions.
• A Progress Map featuring the eight locations in the adventure, where she can track her progress.
• A Visual Guide explaining the different types of clues she will encounter.
• Eight Exciting Missions that will take her through different locations in Villa Jacarandá.
• Mini Multiple-Choice Challenges with explanations to help her review each answer.
• A Brief Recap of the discoveries made during each mission.
• The Complete Solution to the mystery.
• A final Honorary Investigator Certificate.

An adventure that entertains while helping children learn

Designed especially with the interests and maturity of an eight-year-old girl in mind, this book naturally encourages reading comprehension, observation, logical reasoning, critical thinking, memory, information organization, and problem-solving skills.

It also introduces valuable life lessons: learning to separate facts from assumptions, listening to other points of view, avoiding accusations without evidence, working as a team, asking for help, and being willing to change your mind when new information appears.

Why will it feel special to an eight-year-old girl?

Because Luna, the main character, is eight years old too: curious, brave, and determined to uncover the truth. She doesn't always get the answer right on her first try, but she observes, asks questions, and learns from every mistake until she finds the answer.

The reader won't simply watch the story unfold. She will become part of the team, make decisions, and discover that her own observations can lead to the truth.

By the time she completes the adventure, she won't have just solved a mystery. She will have discovered how much she is capable of achieving.

A mystery story, an educational experience, and an adventure that turns every reader into an investigator.

Perfect for curious girls who love puzzles, detective stories, clue-solving games, and books that let them take part in the adventure.

Open the book, grab your pencil, and look closely.

The photograph is hiding a secret. And only a young investigator can uncover it.
