Cora Zeng is a crime scene cleaner, washing away the remains of brutal murders and suicides in Chinatown. But none of that seems so terrible when she’s already witnessed the most horrific thing possible: her sister, Delilah, being pushed in front of a train. Before fleeing the scene, the murderer shouted two words: bat eater. So the bloody messes don’t really bother Cora—she’s more bothered by the germs on the subway railing, the bare hands of a stranger, the hidden viruses in every corner, and the bite marks on her coffee table. Of course, ever since Delilah was killed in front of her, Cora can’t be sure what's real and what’s in her head. She pushes away all feelings and ignores the advice of her aunt to prepare for the Hungry Ghost Festival, when the gates of hell open. But she can't ignore the dread in her stomach as she keeps finding bat carcasses at crime scenes, or the scary fact that all her recent cleanups have been the bodies of East Asian women. As Cora will soon learn, you can’t just ignore hungry ghosts.
