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.
