What appears to be a budding friendship between two moms-to-be brings more than its fair share of unpleasant surprises in this debut psychological thriller.Helen Thorpe has just relinquished her job in advertising to begin maternity leave and prenatal classes. All seems well in her world, snugly cocooned as she is in a bucolic London neighborhood, though she's grappling with an energy-draining summer heat wave, the exhaustion of ongoing house renovations, and pesky calls from a refinancing company. Also, there is the fact that her husband, Daniel-who runs an architecture firm with her brother, Rory-is frequently too immersed in work to accompany her to the prenatal clinic. So when Rachel, a single mother, pops up in prenatal class, Helen welcomes her companionship despite Rachel's sometimes-shocking, often invasive behavior. Multiple narrators-including Helen; Rory's wife, Serena; and Helen's friend Katie, a journalist currently covering a case of sexual assault-drive this suspenseful thriller, and when Rachel turns up on Helen and Daniel's doorstop, inserting herself even further into their lives, things take a decidedly threatening turn. As the story progresses, secret notes, a lost laptop, and old newspaper clippings make it quite clear that something nefarious is afoot. Helen's rising sense of unease is effectively contrasted with her much gentler memories of university days from a decade earlier, when she, Daniel, Serena, and Rory reveled in the glory of their time together.With constantly growing levels of menace, this tension-filled novel will keep you guessing through its final revelations.
