In a near-future city, Sky receives a mysterious signal: 11:11. Soon after, his cat Joy reveals an impossible truth—he can communicate through a forbidden system that is not allowed to make decisions for humans. Together with Aria, Sky learns that this system does not test intelligence or power, but something far more important: conscious choice. Even slowing down or doing nothing turns out to matter. The Joy of the New Earth is a thoughtful science-fiction story for children aged 8–10 about technology, responsibility, and staying in control. It is the opening book of The Cosmic Library, a series where humans remain in charge of their own decisions.
