Four books. One vision. A blueprint for the world we are building together.
The HumanKind Trilogy is a four-book series that begins with a spark — a global movement designed on purpose — and builds toward a complete architecture for human flourishing. Each book stands alone. Together, they form a blueprint for the world we are capable of building.
Written by Mark McFillen over fifteen years of research into behavioral science, emotional physics, and the mechanics of human connection, the series moves from ignition to common ground to a new operating system for the human mind.
Where human nature meets intentional design
The prequel that started it all. A fifteen-year quest to understand why movements ignite — and how to design one on purpose. The blueprint for The Grand Experiment and the Hello World Challenge.
