Pi in the Sky

Joss lives in The Realms, a dimension separate from Earth where his family helps maintain the laws of the universe. As the youngest of seven brothers who all have crucial cosmic jobs, he feels uncertain about his own purpose and place in existence. When Earth and all human memories of it suddenly disappear, Joss becomes entangled in a mission to restore the planet and its inhabitants. He must work with Annika, the only human who remembers Earth existed, to recreate the entire solar system - starting with pi, the mathematical constant that underlies reality. The story combines astronomy, mathematics, and questions about the nature of reality into an adventure across dimensions. Through challenges both cosmic and personal, Joss confronts what it means to find one's role in the vast machinery of the universe. The novel explores themes of self-discovery, responsibility, and humanity's place in the cosmos, all while grounding abstract scientific concepts in relatable human experiences.
