Elsa Cavalon, petrified that the nightmare from 15 years earlier is beginning all over again...

Marin Quinn, hiding with her daughters in their concrete fortress, her storybook marriage over...

Perfect strangers whose once-perfect lives were cruelly shattered, they're bound by a long-lost child, a fragile strand of newfound maternal hope and mutual loneliness. Yet Elsa and Marin are never truly alone. Someone is always nearby, watching them and their children. Someone driven by vengeance and the simple poetry of nursery rhymes.

Someone who must satisfy a dark need with innocent blood. And now time is running out for two mothers stalked by a cunning mastermind who wants to leave them scared to death.
