You Know What You Did

Description

In this heart-pounding debut thriller for fans of Lisa Jewell and Celeste Ng, a first-generation Vietnamese American artist must confront nightmares past and present. . . .

Annie “Anh Le” Shaw grew up poor, but seems to have it all now: a dream career, a stunning home, and a devoted husband and daughter. When Annie’s mother, a Vietnam War refugee, dies suddenly one night, Annie’s carefully curated life begins to unravel. Her obsessive-compulsive disorder, which she thought she’d vanquished years ago, comes roaring back–but this time, the disturbing fixations swirling around in Annie’s brain might actually be coming true.

A prominent art patron disappears, and the investigation zeroes in on Annie. Spiraling with self-doubt, she distances herself from her family and friends, only to wake up in a hotel room–naked, next to a lifeless body. The police have more questions, but with her mind increasingly fractured, Annie doesn’t have answers. All she knows is this: She will do anything to protect her daughter–even if it means losing herself.

With dizzying twists, You Know What You Did is both a harrowing thriller and a heartfelt exploration of the refugee experience, the legacies we leave for our children, and the unbreakable bonds between mothers and daughters.
