Fourteen-year-old Ama and her suburban American community have been trapped in a daylong infinite loop that always ends with a bang—a nuclear blast that kills everyone in their town—only to reset and start the day all over. Over the lifetimes that have passed through the infinite loop, Ama has “accumulated” super strength, agility, and speed. Meanwhile, Ama’s brother Ike has gained genius level intellect. Over the many lifetimes in the Loop, Ama has become known as the “Knife Queen” for her superior skills of mass murder in her town she accomplishes exploiting her accumulated physical prowess. She befriends and regularly spars with (and sometimes tortures) Carl, a classmate who used to racially bully her because of her Blackness. Over the lifetimes of loops, Carl has also accumulated impossible physical prowess. After one loop, Ama has a new dream of her late mother, which surprises her. The dream demonstrates to Ama that there are cracks in the cycle of infinite violence she is caught in as the “Knife Queen”; she had a mother who cared for and loved her before the nuclear holocaust killed everyone and set their neighborhood into the infinite loop. Ama goes about her usual routine, cycling around the neighborhood with her brother Ike, torturing neighbors and sparing with Carl to the death. Usually Ama and her family members would get killed or kill themselves before the nuclear holocaust—known as the Flash—would kill everyone at the end of the day and reset the Loop. But Ama, her brother, and father lean against the westward facing walls to experience the Flash. They pose so that when the blast strikes and bleaches the walls around them, their fun pose will leave a funny image behind. Even with the neverending end of the world, one feels silly and scared; but in the company of one’s family, Ama reflects, at least one doesn’t feel alone.
