In this fluid society, human and mindship avatars mingle in corridors and in function rooms, and physical and virtual realities overlap, the appareance of environments easily modified and adapted to interlocutors or current mood. A transport ship discharged from military service after a traumatic injury, The Shadow's Child now ekes out a precarious living as a brewer of mind-altering drugs for the comfort of space-travellers. Meanwhile, abrasive and eccentric scholar Long Chau wants to find a corpse for a scientific study. When Long Chau walks into her office, The Shadow's Child expects an unpleasant but easy assignment. When the corpse turns out to have been murdered, Long Chau feels compelled to investigate, dragging The Shadow's Child with her. As they dig deep into the victim's past, The Shadow's Child realises that the investigation points to Long Chau's own murky past--and, ultimately, to the dark and unbearable void that lies between the stars...
