There is a question that changed the world more than two thousand years ago. What if it had been erased before reaching us?

Athens, 450 BC. Will, Mia, Leo, Sophie, and Max-the Adventure Crew-land in the heart of the civilization that taught humanity how to think. The streets smell of olive oil and freshly cut marble. The Parthenon is still being built on the Acropolis. And in the center of the Agora, barefoot, with a worn-out tunic and dust-covered feet, a man named Socrates is about to ask the most dangerous question in all of human history.

Except this time, someone wants to stop him from asking it.

A stranger has arrived in the city selling the irresistible promise that wisdom can be measured, weighed, and proven by a machine, and that anything that doesn't fit into numbers is worthless. Geometry? High value. Poetry? Zero. Philosophy? Dangerous. And while the crowd applauds the spectacle, the smartest children in Athens begin to feel ashamed of doing the only thing they have always done well: asking questions.

The Adventure Crew recognizes this scent. It's the same old enemy, with a new disguise and a plan more dangerous than any they have faced before. Because this time, the target isn't a city, a treasure, or an army. The target is an idea. And if that idea is erased before it reaches a young man named Plato, Western philosophy, science, democracy, and everything that follows simply... never happen.

To prevent this, the children will need much more than courage. They will need to understand what it truly means to have wisdom and prove it in front of the entire city, in a confrontation that will pit questions against certainties, doubt against arrogance, and a crew of time travelers against a machine that insists that anything that cannot be measured does not deserve to exist.

Along the way, the crew will meet Dion, a young potter boy who paints stories on his father's amphorae-until the stories begin to disappear from the city, and the amphorae are left blank. They will race through the alleyways of the Agora, hide ancient secrets from the wrong hands, climb up to the Theater of Dionysus for a plan as bold as Greek mythology itself, and discover firsthand what Socrates already knew: that the courage to not know is the first step toward any true wisdom.

This is the seventh book in a saga that has already won over thousands of families around the world, written to ignite in children aged 8 to 12 the flame that every child is born with: the desire to ask why.

Each chapter of the Adventure Crew: Time Travelers series dives deep into real history, with authentic characters, places, and events treated with respect and accuracy, without ever losing the rhythm of adventure, humor, and emotion that makes any child turn the page late into the night, begging for "just one more chapter." Here, learning history isn't about memorizing dates. It's about living inside them.

The Olympiad of the Gods is both a thrilling adventure and a quiet conversation between parents and children about the value of asking, doubting, and not being ashamed of not knowing, in an era where ready-made answers are everywhere and genuine curiosity has become far too rare. It's the kind of book a child finishes reading and looks at you with a new question in their eyes. And that is exactly what makes it different.

You don't need to have read the previous books in the series to dive into this adventure. Each volume works as an independent door to a different era in history, though fans of the saga will joyfully recognize every detail that connects the seven books. Families who already follow the Adventure Crew know: each new chapter is treated at home as an event, anxiously awaited, read aloud, and discussed at dinner.

If you are looking for a gift that a child will open with true enthusiasm, Socrates asked a question that crossed two thousand five hundred years.
