The Chrysalis Generation-III Habitat

For ninety-five years, the lie was their home. Zara Carter knows only the grey walls of Sanctuary 66, the daily ration paste, and the Overseer's soothing broadcasts: the outside world is dead. Poisoned. Forever lost. But when Zara uncovers forbidden files, she discovers a truth that shatters her existence. Sanctuary 66 is not a shelter. It is the "Chrysalis Generation-III Habitat"-a lifelong psychological experiment.
The surface has been habitable for decades. And the countdown to the scheduled "termination" of all inhabitants has already begun. Trapped in a perfect prison and watched by a fanatical Overseer who would rather flood the vault with nerve gas than see his experiment fail, Zara's only chance is to unlock the door that has been sealed since her birth. But the freedom she finds is no paradise. It is a mysterious, haunting world with wonders and horrors of its own-and the chilling certainty that her prison was not the only one.
A gripping psychological sci-fi thriller for fans of Wool and Dark Matter. A story about the ultimate betrayal, the courage to seek the truth, and the terrifying price of freedom.
