THE STRANGER IN THE MIRROR

An amnesia victim has built a near-perfect new life when she runs into someone from her past.

A disheveled, bleeding woman who doesn't know even her own name is picked up hitchhiking on a highway in New Jersey by a kindly trucker. He and his wife become her surrogate parents, helping her manufacture a new identity as Addison Hope. Addison soon meets Gabriel, a wonderful young man from the Philadelphia Main Line who is so smitten he ends a yearslong relationship with another woman and proposes. Gabriel's mother, Blythe, isn't ready to pop the champagne, though—she wants to know who this girl really is. In truth, Addison feels the same reservations. Meanwhile, up in Boston, a handsome psychiatrist named Julian is caring for his 7-year-old daughter on his own after his wife disappeared two years earlier. Could it be...? In their fifth outing, the sisters who write as Constantine have cooked up another plot involving people with hidden identities—and it works well to embed that issue in the head of the protagonist, who doesn't know herself or anyone else from her past. The plot is twisty but not excessively so—it's the kind where an experienced reader can enjoy staying a few steps ahead of the reveals rather than the kind where the answers are obvious too early or are based on too many late-breaking details. Like most of Constantine's work, including fan favorite The Last Mrs. Parrish (2017), this one is set in the lap of luxury, this time a bit stripped down: fewer ritzy locations and rich-people caricatures, a bit less wealth porn. Still, Gabriel's country-club-snob mother is one of the best characters, and one of several wine recommendations is slipped in as the villain is about to enter his secret den of psychosis: "I have the house to myself overnight for the first time that I remember, and have decided to open the Odette Estate Reserve...."

A fast, fun read for domestic thriller fans.
