In this "wicked slow burn" (Entertainment Weekly) of psychological suspense, a woman becomes fixated on her neighbor--the actress.

Though the two women live just a few doors apart, a chasm lies between them. The actress, a celebrity with a charmed career, shares a gleaming brownstone with her handsome husband and three adorable children, while the recently separated narrator, unhappily childless and stuck in a dead-end job, lives in a run-down, three-story walk-up with her ex-husband's cat.

As her fascination with her famous neighbor grows, the narrator's hold on reality begins to slip. Before long, she's collecting cast-off items from the actress's stoop and fantasizing about sleeping with the actress's husband. After a disastrous interaction with the actress at the annual block party, what began as an innocent preoccupation turns into a stunning--and irrevocable--unraveling.

A riveting portrait of obsession, Looker is "a sugarcoated poison pill of psychological terror" (The Wall Street Journal) and an immersive and darkly entertaining read--"by the end you'll be gasping" (People).
