At the start of Giffin's latest, following All We Ever Wanted (2018), Cecily Gardner is out late one night in May of 2001, trying to recover from heartbreak. She wanders into a dive bar in Manhattan, and nearly calls her ex-boyfriend, until she's interrupted by a handsome stranger. Cecily is immediately taken with Grant, and the two chastely spend the night together. Over the course of the next few months, Cecily gets to know Grant, who is focused on caring for his brother, Byron, who is afflicted with ALS. Cecily and Grant's feelings for each other deepen, and then the unthinkable happens on 9/11, and Cecily can't reach Grant, who works in one of the World Trade Center towers. Cecily is left reeling, and then two more things further shake her world: her ex comes back into her life, and she discovers a missing-person poster with Grant's picture on it. As she learns who is searching for him, Cecily discovers how little she knows about Grant. Giffin keeps the twists and turns coming fast and furious in her absorbing new outing.

Giffin's suspenseful but sometimes unconvincing latest (after All We Ever Wanted) opens in May 2001, a week after 28-year-old reporter Cecily Gardner breaks up with her commitment-averse boyfriend. Lonely and sleepless, she makes a late-night visit to a bar, where she feels a sudden connection with an attractive stranger. They spend the night in Cecily's apartment, agreeing not even to kiss. The stranger, Grant Smith, tells Cecily that he's a Wall Street trader whose twin brother is dying of ALS, and she trusts him enough not to ask further questions about his life. Soon deeply in love, they spend nights and a weekend together, still holding off on sex, before Grant leaves for London, where his brother is enrolled in a clinical trial. Cecily sees Grant on September 10, the night he returns, but can't reach him after the towers fall. When she sees his face on a "missing" poster and calls the number listed there, her certainty about him and their bond is thrown into doubt. Though the bizarre decisions made by Cecily and Grant stretch plausibility, and the use of 9/11 reads as a plot contrivance, Giffin holds the reader's interest with solid pacing and fine style. Compared to Giffin's past work, this disappoints. (June)
