What do you try to save when your world falls apart? Gareth L. Powell’s first collection of short fiction features a motley collection of archaeologists, hackers and ex-cops struggling to answer that very question. As their lives implode around them, will they use the moment to save their own skins, or to find a way to make up for past misdeeds? With settings ranging from the dead sands of Mars to the seedy backstreets of Amsterdam and Buenos Aires, these fifteen action-packed tales explore mind-bending science fictional ideas through the eyes of unforgettable and all-too-human characters.
