Every six months a siren blares in Bryniard: Another victim. Another death.
No one knows why people die, aging to death in twenty-four hours. All they know is that this mysterious illness that’s been claiming their lives for generations acts with no mercy or warning.
Unlike the rest of Bryniard, Alissa Kriegen had learned to live not only with the terrible tragedies that devastated her people, but with a secret she had kept for all of her life: the ability to predict who the next victim will be.
When Alissa's worst fear comes to life and her own daughter is marked for death, she has only one choice: cross the walls protecting her town from the monsters outside in hopes to save her child.
Caught in a new world where everything she knows to be true is questioned, Alissa will learn the price of saving a life would be to sacrifice her own principles. While running against time itself, she will have to confront the ultimate question:
How far will she go to save the life of her daughter?
