Maiga wants to vanish. She wants to leave Hollow Jimmy before someone recognises her and remembers her part in the events that led to the human race being all but wiped out. Though the station is a sanctuary, she knows there's a new home elsewhere in the darkness. But others have plans too, for Maiga and for Hollow Jimmy. Their fates are about to be intertwined.

Captain Bara wants revenge. Perhaps that will silence the noises only she can hear aboard her ship, the Trebuchet. A ship whose name is becoming a curse to those who would like to see humanity finished off once and for all. For Bara, Hollow Jimmy is not a sanctuary. It's a fortress. It's a place for her to start a war.

The first battle is for Hollow Jimmy itself. A power struggle between opposing factions for the hearts and minds of the humans of Hollow Jimmy. A fight against an enemy neither woman has faced before – their fellow humans.
