Anna O'Donnell's health continues to deteriorate.

Nurse Lib Wright turns to Sister Michael for help - only to find support in an unexpected place...

Anna’s fast began as a self-inflicted and earnest expression of faith - subsisting only on what she calls "manna from heaven". Locals in her small rural village of 1850s Ireland are baffled while tourists flock in their droves.

Nurse Lib has been hired to determine whether or not Anna is a fraud. Can she get to the root of why the child may actually be the victim of murder in slow motion..?

Emma Donoghue’s magnetic novel is a tale of two strangers transforming each other's lives, a powerful psychological thriller, and a story of love pitted against evil in its many masks.
