"Just let him go." Ky Tran will forever regret these words she spoke when her parents called, asking if they should let her younger brother Denny out to celebrate his high school graduation with friends. That night, Denny is brutally murdered inside a busy restaurant in the Sydney suburb of Cabramatta, a refugee enclave facing violent crime, a racist police force, and the worst heroin epidemic in Australian history. Ky learns that the police are stumped by Denny’s case: a dozen people were at the restaurant when Denny died, but all claim to have seen nothing.  Ky sets aside her grief and determines to track down the witnesses herself. With each encounter, she peels back another layer of the place that shaped her and Denny, exposing trauma and seeds of violence that were planted well before that fateful celebration dinner. Alternating between Ky’s voice and the perspectives of the witnesses, Tracey Lien’s extraordinary debut is at once heart-pounding and heart-rending as it probes the intricate bonds of friendship, family, and community through an unforgettable cast of characters, all connected by a devastating crime.
