Hiding on Hyperion Eagle, Robyn, Hawk and Starling play a game of hide-and-seek around Saturn. Eagle quickly finds everyone except Starling, whose engines have frozen shut while she hides inside an icy cave on the moon Hyperion. Starling is cold, frightened, and marooned in the cave, but she can still relay her observations via radio. Using the minimal clues she’s able to provide, the other Racers have to methodically search every single cave on the pockmarked moon to find Starling and rescue her. Will they be able to find her before their own engines freeze shut?
