The peripheral

In the near future in a broken-down rural America, Flynne Fisher scrapes a living as a gamer for rich players. One night, working a game set in a futuristic but puzzlingly empty London, she sees a death that's unnervingly vivid. Soon after she gets word that it isn't a game after all - the future she saw is all too real, she's the only witness to a murder and someone from that unreal tomorrow now wants her dead.
