Hazel and the reawakened command AI have repaired Daedelus, the vast generation ship carrying the last of humanity on a centuries long journey to a new world. But can she convince her people of the truth she learned in the process? That humanity is not alone on Daedelus. That the Yi, an alien species, have made it their home.

But those in power don’t want to listen if it means a challenge to their authority. So Hazel must travel again to the ship’s far reaches, to learn what the Yi plan for Daedelus. What she discovers there is far more terrifying than a mere hole in the sky…
