Power-hungry dictators have broken the world and placed humanity's future at risk.

Twelve-year-old Zoë knows nothing of these upheavals and political struggles. She has lived a solitary, fantasy-filled life in pastoral Germany, and is completely unprepared when a sudden, devastating attack destroys her peaceful existence.

With the most important question of all.
