When Eli discovers a forgotten mural hidden beneath his apartment building, he and a small group of unlikely friends uncover something far greater than they ever imagined — a hidden network once known as The Light Keepers. As loneliness, fear, and silence quietly spread through the city, the children begin noticing the people adults no longer seem to see: the forgotten, the hurting, the lonely, and the lost. Guided by old lanterns, hidden tunnels, rooftop signals, and a growing sense that light still matters, the new Light Keepers must learn what it truly means to stand together in a fractured world. Filled with mystery, adventure, friendship, courage, and hope, Book One: The Quiet Crack begins an unforgettable journey about carrying light into places where darkness has made people feel invisible. Because sometimes the smallest lights are the ones that help people find their way home.
