Do you ever wonder where all the bells went?

There was a time when bells were everywhere-tower bells, school bells, town bells-ringing out across cities and villages, marking time, calling people together.

But then, they started to disappear. Melted down, people said. Forgotten, replaced, left to rust in empty towers.

But what if there's more to it?

What if bells weren't just instruments of sound? What if they held power-power hidden in their resonance, power that some would do anything to control?

When 10-year-old Theo Hollander, a curious young tinkerer, discovers a mysterious bell with strange abilities, he uncovers a forgotten family legacy tied to the lost art of resonance. Alongside his sister Ella and his friends Miles, Clara, and Duncan-members of their inventive group, the Tinker Society-Theo begins to unravel secrets buried for generations, hidden in journals, blueprints, and echoes of the past.

But the deeper they dig, the greater the danger grows. Someone-or something-wants the bells' secrets for themselves. With time running out and the power of resonance teetering on the edge of control, Theo and his friends must rely on their wits, courage, and each other to protect the truth and uncover what it truly means to be a Chimekeeper.

In a thrilling mix of science, magic, and adventure, Theo discovers that some mysteries refuse to stay silent-and sometimes the smallest sound can change everything.
