The city of Orokos has been lashed by probability storms-violent tempests that change whatever they touch. When a probability storm hits, streets are rearranged, children are turned to glass, rivers break from their banks, and life suddenly becomes death. Nothing is stable. Everyone is vulnerable. Rail has struggled with the effects of one such storm for years; when he was hit, he lost the ability to breathe freely. Moa has also seen her share of struggle-as the daughter of dead rebels, as an outcast, as a criminal. Now they have uncovered their first taste of fortune: a strange artifact wanted by the most powerful peopl in the city. As with most fortunes, this one comes with a price. The mysterious object is a gift to any thief. But could it be more? Rail and Moa will have to run, fight, double-cross, steal, and dodge the storms in order to find out . . . and unlock Orokos's deepest, most dangerous secrets.
