Earth is dead. In desperation, humanity has fled their birthplace, seeking out a new home among the stars. After millennia in space, they find hope in the form of an ice-covered planet called Pan Ku. Sixteen year old Ji, a botanist, now works tirelessly to terraform the planet before the ark ship that carried humanity there gives out. However, during a routine mission, disaster strikes and leaves Ji stranded in a strange sector of space, far away from anyone she's ever known. Before long Ji finds herself caught up in a conflict she has no part in, imprisoned on a planet she didn't know existed, surrounded by beings she never could have imagined. Now it's up to Ji not only to save her people, but to save herself.
