Like its predecessor, Shift, Control crackles with energy, driving the story forward with cutting prose. Curran picks up where Shift left off, with Scott Tyler working – hard – at his job, keeping his relationship alive, and hiding the more unusual aspects of what happened during the climax of Shift.. Scott and his partner are sent off to hunt the adults who can still Shift. Some of them come quietly. Some of them don’t. Frank Anderson, the last adult Shifter, proves to be particularly difficult to catch, what with her special powers and the fact that she’s playing a deep, dangerous game.
