    For grown-ups

    Every explorer is welcome.

    No prerequisites. No gatekeeping. Whatever a child already knows, there is a way in — a story to follow, a character to love, and a real IoT idea waiting underneath. That is the whole promise of the series: no one left behind.

    All sixty covers are finished, and the books are illustrated and released a world at a time. Seventeen are ready to read today.
