Some people call flashes a blessing, others call it an advantage given to the unworthy. Pain is only in the eyes of the beholder, I suppose. Elliott Owens has been blessed with the flashes, or rather, cursed. Flashes of his past life, triggered by familiar objects or people. Thousands of people, living with the flashes, scattered across the world, being collected like stones by the goverment for testing.
Those with flashes are classified into three groups, similar to how you classify animals. The cures, the experiments, the runaways. Elliott is a runaway, of course, did you think he would willingly become a goverment pawn?
Years of hiding and testing later, a cure was discovered. A cure that could stop the flashes, but start something worse. Something much, much worse. And as the world becomes a mess of fear and chaos, the only few survivors left consists of a guilty scientist and a stupidly ambitious runaway.
