Antwan Carter is thirteen years old, autistic, and remembers everything he has ever seen — perfectly, permanently, whether he wants to or not. From a crawlspace in their Chicago apartment, he hears his mother Denise murdered. Three men. Every sound. A memory he will replay for the rest of his life. Then he finds her phone — full of photos of the men responsible: Roland "Ro" Banks, the gang leader who ordered it; Elliot Vance, the mayor's assistant, who helped carry it out; and the three-man crew who did the killing. Antwan does what his brain was built to do. He studies. Anatomy. Surveillance. Entry. Threat assessment. He memorizes everything about how killers work — and then he hunts every one of them down, one by one, while a homicide detective slowly realizes the methodical killer emptying the city's underworld is a child. But when Detective Ruiz finally closes in, the arrest doesn't go the way anyone expects — because the federal government has been watching too, and it doesn't put assets in cells. Mayor Catherine Hale survives. The file stays open. And Antwan Carter is just getting started.
