In this action-packed thriller from the New York Times bestselling author of The Midwife Murders, a mother-to-be sees the women in her social circle start to disappear—and she could be next . . .

Emily Atkinson leads a complicated life in New York City. She's a successful marketing executive who lives in a luxury apartment and enjoys a glamorous existence until she lands in the hospital with a double diagnosis: she parties too much—and she's pregnant. Her nurse and new best friend, Betsey, helps Emily rediscover how much she loves morning runs in the park and quiet nights at home. But as a series of women in her wealthy social circles go missing, Emily's pregnancy becomes decidedly high-risk.
