Caves of Aṭlāl Bābil (Unabridged‪)‬

Sara Lafeete struggles to complete her work shift installing wiring in the ship's tunnels on the asteroid Psyche. Exhausted and suffering from the initial stages of radiation poisoning, she takes a detour back to the base through an ancient lava tube. Suffering from radiation brain fog, she takes a wrong turn and becomes lost as her radiation levels spike further.

Salaam Rahal detects energy readings on orbital paths that will intersect with Psyche. Faced with a possible attack, Commander Calager McGeen must defend the base and leave Sara to her own devices. Sara stumbles across what could be a fantastic discovery, or is it an hallucination? Can Sara find her way through the lava tubes back to the base? Or will she die a slow, lonely death?
