In Dong's vertiginous debut, a mentally unstable woman stumbles across a conspiracy. After Katrina Kim flunks out of college, she returns to her family's home in Pleasance Village, Illinois, seeking solace; her father sends her away, however, suggesting Katrina stay at a hotel or a friend's house. Katrina goes to the local library and parks, curling up in her car's back seat while her mind retreats into Mi-Hee and the Mirror-Man, her favorite Korean children's book. Like Katrina, Mi-Hee is a lonely girl with compulsive tendencies, but Mi-Hee can access a fantasy world via her kitchen door and has a truth-revealing spyglass. Determined to create her own new existence, Katrina drives to Grand Station, gets an office job, and moves in with a stranger who saw her plea for help on Craigslist and took pity. The stress proves too much, and Katrina starts dissociating, layering Mi-Hee's "kitchen-door world over [her] own, like a colored pane of glass." She develops elaborate protection rituals and starts following co-worker Kurt Smith because she thinks they're connected. Then, one night on the Cayatoga Bridge, Katrina sees Kurt crash his SUV. He extricates himself, screams at Katrina for ruining things, and jumps off the railing. Katrina tells the police, who dismiss her, but when Kurt misses work on Monday, Katrina launches her own investigation, uncovering a reality far stranger than her inner fictions. Events unfold courtesy of Katrina's anxious, unmoored first-person present narration, keeping readers off-kilter. Some characters lack depth and verisimilitude, but Katrina's fraught relationship with her immigrant parents rings true. Though the setup drags on, sapping the book's momentum, once the mystery drops into gear, increasingly bonkers twists propel the story to a cogent, poignant close. A rabbit hole worth falling down.

One day, she finds a postcard with a threatening message in his desk drawer. Terrified it's directed at her, she drives at midnight to the bridge she regularly visits, to perform the most potent of her self-soothing rituals. Then Kurt shows up, shouts some words of blame, and jumps to his death. Katrina is horrified and baffled. How does he know of Katrina's visits to the bridge? Was he surveilling her even as she surveilled him--and who is he really? Katrina's search for answers reveals secrets all around her. This nuanced depiction of a woman's struggles with isolation and mental health rings entirely true. Fans of sharp, inventive fiction will be eager for Dong's next. Agent: Amy Bishop, Dystel, Goderich & Bourret. (Jan.)

Dong's twisty debut follows Katrina Kim, who struggles with obsessive-compulsive tendencies and an unhealthy fascination with her coworker Kurt. Katrina doesn't think of herself as a stalker, but even so, she searches through Kurt's desk and is sure they have a special connection. When she finds a cryptic message implying that he's aware of her surveillance, she panics. Things get much worse when Kurt apparently dies from suicide and blames Katrina for it. Katrina's world starts to implode, and everything she once thought she knew seems suspect. It is challenging to follow Katrina as her sanity unravels. She is equally frustrating and heartbreaking--the perfect example of an unreliable narrator who actively destroys her relationships and delivers varying versions of the truth, even to herself. Narrator Hannah Choi brings Katrina's story to life with outstanding characterizations and superb pacing. The intimacy of the first-person narration further draws listeners into Katrina's increasingly unsettled mind. VERDICT This fast-paced, surreal tale will hook listeners from the beginning. A perfect fit for fans of Gone Girl and Girl on the Train.--Victoria Kiszka
