Winner of the Agatha and Anthony Awards
A heart-stopping thriller for fans of Lisa Jewell and Celeste Ng.
Annie "Anh Le" Shaw has built the perfect life: a rising star in the art world, a devoted husband, a beautiful daughter. She's left her past behindβor so she thought.
When her mother, a Vietnam War refugee, dies without warning, Annie's carefully controlled world begins to unravel. The obsessive-compulsive disorder she fought so hard to overcome returns, and now it's darker and more dangerous than ever.
Now her intrusive thoughts aren't just thoughts.
They're coming true.
A powerful art patron vanishes, all eyes turn to Annie, and things begin to unravel fast.
She wakes up in a hotel room. A dead body beside her.
No memory of how she got there.
With suspicion closing in and her mind betraying her, Annie must piece together the truth before it destroys her. But the deeper she digs, the more she's forced to confront buried secrets about her past, her family, and the trauma she thought she'd escaped.
A gripping, twist-filled psychological thriller about obsession and the lies we tell ourselves.
