Chased through the Golden Wastes by a krill, a Sky Kid stumbles into a portal that tears him from his world of light-and drops him into a cold, unfamiliar cave. There, he finds Tim Drake bound in chains. Thrown together by fate, the child must learn to survive in a strange and dangerous world, while Tim struggles to adapt to a role he never expected-caring not only for himself but also for a lost child of the stars. In the fragile balance between light and shadow, they begin to forge a bond that could change them both forever.
