Kirkus: A minute-by-minute account of mass murder at a high school by a former student. Four students from a range of different backgrounds at Alabama’s Opportunity High, all of whom have a history with Tyler, the gunman, take turns telling this harrowing story in the first person. They include his sister, Autumn, and her clandestine girlfriend, Sylv, who have only each other for solace as the home lives of both are in upheaval. Tomás, Sylv’s brother, recounts his and his friend Fareed’s desperate efforts to help from outside the school’s auditorium, where their fellow students and teachers are locked in with Tyler as he picks them off one by one. Finally, Claire, Tyler’s ex-girlfriend, realistically agonizes over what to do when she and a few others outside running track realize that the gunshots they hear are coming from inside the school. Grounded in the present, the story makes effective use of flashbacks that lay bare the pain and deception that have led up to the day’s horror. The language can occasionally feel a bit melodramatic, with lines like “we’re fighting for hope and a thousand tomorrows,” but this is a minor side note to this compelling story of terror, betrayal, and heroism. This brutal, emotionally charged novel will grip readers and leave them brokenhearted.
