Sixty years after the destruction of Earth, twenty-two-year-old Maren "Inferno" lives on the spaceship Reverence under thirteen laws designed to control the population. When she overhears a secret that threatens her life, she flees to a mining compound on the toxic surface of Earth in search of the sister ship, Liberty. Her mission is to recover what was stolen from Reverence to attempt to earn a pardon.

Instead, Maren discovers a truth that shatters her worldview and finds love with Kai, a man from the enemy ship who is as dark as space itself. Maren realizes the true enemy is the generational lie shaping her society.
