Best-selling author Rick Riordan presents Yoon Ha Lee's space opera about thirteen-year-old Min, who comes from a long line of fox spirits. But 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. 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.
