THIRTEEN-YEAR-OLD MIN comes from a long line of fox spirits. But you'd never know it by looking at her. To keep the family safe, Min’s mother insists that none of them use any fox-magic, such as Charm or shape-shifting. They must appear human at all times. Min feels hemmed in by the household rules and resents the endless chores, the cousins who crowd her, and the aunties who judge her. She would like nothing more than to escape Jinju, her neglected, dust-ridden, and impoverished planet. She’s counting the days until she can follow her older brother, Jun, into the Space Forces and see more of the Thousand Worlds. When word arrives that Jun is suspected of leaving his post to go in search of the Dragon Pearl, Min knows that something is wrong. Jun would never desert his battle cruiser, even for a mystical object rumored to have tremendous power. She decides to run away to find him and clear his name. Min’s quest will have her meeting gamblers, pirates, and vengeful ghosts. It will involve deception, lies, and sabotage. She will be forced to use more fox-magic than ever before, and to rely on all of her cleverness and bravery. The outcome may not be what she had hoped, but it has the potential to exceed her wildest dreams.

Sebin, a young tiger spirit from the Juhwang Clan, wants nothing more than to join the Thousand World Space Forces and, like their Uncle Hwan, captain a battle cruiser someday. But when Sebin's acceptance letter finally arrives, it's accompanied by the shocking news that Hwan has been declared a traitor. Apparently, the captain abandoned his duty to steal a magical artifact, the Dragon Pearl, and his whereabouts are still unknown. Sebin hopes to help clear their hero's name and restore honour to the clan. Nothing goes according to plan, however. As soon as Sebin arrives for orientation, they are met by a special investigator named Yi and his assistant, a girl named Min. Yi informs Sebin that they must immediately report to the ship Haetae and await further instructions. Sebin finds this highly unusual, but soon all protocol is forgotten when there's an explosion on the ship, the crew is knocked out, and the communication system goes down. It's up to Sebin, three other cadets, and Yi and Min to determine who is sabotaging the battlecruiser. When Sebin is suddenly accused of collaborating with the enemy, the cadet realizes that Min is the most dangerous foe of all...
