Run by Blake Crouch is a thriller that dips its toe just far enough into the world of science fiction to be deeply unsettling. In the lower 48 states of America, an aurora borealis has beamed brainwashing light into the eyes of unwitting citizens, turning them into homicidal, cultish maniacs.
Crouch’s story follows a single family, the Colcloughs. After a narrow escape from several people of murderous intent, they head north from their home in Albuquerque, New Mexico, looking for anywhere that could provide shelter. For the entirety of Run, Crouch focuses on the beat-to-beat action of their journey, providing a ground-level view of the world going to hell, through the eyes of one family in a greater apocalypse.
Those affected by the aurora can spot others affected, but the unaffected are none the wiser, which makes every encounter with humans outside the family a chance encounter with death. The various antagonists in Run are psychopathic and brutal: Those affected by the aurora enjoy killing those who are not. They hack their victims with knives, burn them at the stake or crucify them, and there is no hesitation or regret during their assault—they even go so far as to joke with one another while slaughtering their victims. They also instinctively work together, forming bands of roving vehicles that round up the unaffected for mass execution. All of this sets the tone for the Colcloughs (and the reader) early on: There is no negotiating or appealing with these aggressors. The result is a sense of absolute, uncompromising fight-or-flight.
In the midst of this extreme and violent world, our protagonists are incongruously human, grounding the story in realism. Patriarch Jack is struggling to reconnect with his wife, Dee. Their daughter, Naomi, is an angsty teen who hasn’t felt close to her father in years. Their son, Cole, is a child, too young to really understand what is going on but too old to forget the images he will most likely carry forever. Each of the characters feels realistic: Naomi never wanders into “You just don’t understand me” tropes, nor do Jack and Dee devolve into petty, drama-for-drama’s-sake arguments.
