It takes place during the beginning of World War I, following a 17-year-old British girl named Sasha who has premonitions of death.

Seventeen-year-old Alexandra "Sasha" Fox is the privileged daughter of a respected doctor living in the wealthy seaside town of Brighton, England.

However, working in the hospital soon confirms what Sasha has suspected since a strange incident when she was a young child-- she can sense when someone is going to die.

As her premonitions begin to grow in strength, Sasha sees through them the brutal horrors on the battlefields of the Somme, and the faces of the soldiers who will be killed.

Posing as a military nurse, Sasha goes behind the front lines searching for Thomas, risking her own life as she races to find him, and somehow prevent his death.
