She's ten years old. Her best friend is a broken robot. And the survival of the colony might depend on them both.Luma was a very young child during the Breaking-after the adults forgot, after the machines failed, after the skies went silent. Now, she spends her days fixing broken tech and her nights dreaming of restoring what once was. When she uncovers a damaged robot buried in the old transit hub, Luma's world begins to shift. The robot-glitchy, half-remembering-speaks of failing systems and old threats never truly gone. With time running out and something watching from the shadows, Luma, her best friend Nessa, and the robot known as Echo must brave the tunnels beneath the colony to uncover the truth-and decide what's worth saving.
