THE LEARNING LEGENDS UNIVERSE BOOK 3: THE Pi ENGINE

The Learning Legends Universe

Book Three: The Pi Engine**

What if the world’s smartest systems couldn’t save us?

When Sage starts noticing that children—and adults—are trapped in endless scrolling, optimisation, and invisible pressure to continue, the Learning Legends are drawn into their most dangerous journey yet. Guided through hidden worlds of science, industry, and number, they uncover a truth far deeper than code or calculation.

From the mills of the past to the mines of the present…
From perfect equations to imperfect lives…
From limitless progress to human limits…

At the heart of it all lies the Pi Engine: a flawless system that never finishes, never rests, and never asks whether it should.

As the children descend into Numeria—the realm of logic, algorithms, and endless approximation—they discover a frightening truth: systems can be powerful, useful, and completely indifferent to human suffering. Science can explain how the world works… but not why we matter.

Then something unexpected happens.

Not an upgrade.
Not a better system.
But Good News.

In a story that gently weaves real science, ethics, and Christian theology, The Pi Engine leads readers to a profound revelation: freedom does not come from optimisation, but from truth—and the truth is not a formula.

Perfect for readers aged 9–12 (and the adults who read with them), this richly imagined novel explores:

• technology and attention in the modern world

• stewardship, sustainability, and responsibility

• the beauty and limits of mathematics and science

• and the hope at the heart of the Christmas story

With warmth, humour, and depth inspired by C.S. Lewis, The Pi Engine invites children to think deeply, rest bravely, and rediscover why Joy to the World really matters.

Because the Saviour didn’t come to fix the system.

He came to set us free.
