Once she has her grip on you, she'll never let you go.

At four months old, Olivia Dahl was almost murdered. Driven by haunting visions, her mother became obsessed with the idea that Olivia was a changeling and that the only way to get her real baby back was to make a trade with the “dead women” living at the bottom ofthe well.
Now Olivia is ready to give birth to a daughter of her own … and for the first time, she hears the women whispering.

Everyone tells Olivia she should be happy. She should be glowing. But the birth of her daughter only fills Olivia with dread. As Olivia’s body starts giving out, slowly deteriorating as the baby eats and eats and eats, she begins to fear that the thing she gave birth to isn’t her daughter
at all and, despite her best efforts, history is repeating itself.

Soon, images of a black-haired woman plague Olivia’s nightmares, drawing her back to the well that almost claimed her life—tying mother and daughter together in a desperate cycle of fear and violence that must be broken if Olivia has any hope of saving her child … or herself.
