Cora Zeng is a crime scene cleaner, washing away the remains of brutal murders and suicides in Chinatown. The bloody messes don't bother her, not when she's already witnessed the most horrific thing possible: her sister being pushed in front of a train. Before fleeing the scene, the murderer whispered two words: bat eater. Months pass, the killer is never caught, and Cora can barely keep herself together. She pushes away all feelings, disregards the bite marks that appear on her coffee table, and won't take her aunt's advice to prepare for the Hungry Ghost Festival, when the gates of hell open. Cora tries to ignore the rising dread in her stomach, even when she and her weird co-workers begin finding bat carcasses at their crime scene clean-ups. But Cora can't ignore the fact that all their recent clean-ups have been the bodies of East Asian women. Soon Cora will learn: you can't just ignore hungry ghosts.

A psychological thriller about two teenagers teaming up with the FBI to track down juvenile serial killers. In 1982, two teenagers—serial killer survivor Emma Lewis and US Marshal candidate Travis Bell—are recruited by the FBI to interview convicted juvenile killers and provide insight and advice on cold cases. From the start, Emma and Travis develop a quick friendship, gaining information from juvenile murderers that even the FBI can't crack. But when the team is called in to give advice on an active case—a serial killer who exclusively hunts teenagers—things begin to unravel. Working against the clock, they must turn to one of the country's most notorious incarcerated murderers for help: teenage sociopath Simon Gutmunsson. Despite Travis's objections, Emma becomes the conduit between Simon and the FBI team. But while Simon seems to be giving them the information they need to save lives, he's an expert manipulator playing a very long game...and he has his sights set on Emma.
