Ashme is a New Mesopotamian-a "Meso." She dreams of being a hero, fighting against the brutal Ostarrichi ruling her country. She is an indigo child, her DNA modified by sentient AI, enabling her to control computer systems at will. With this power, she has something to offer the Meso resistance. Her twin brother, Shen, however, suffers from a neurological disorder and needs someone to care for him. Increasingly, that task falls on her.

How can she become the hero her people need when her brother's needs are overwhelming? If she continues caring for Shen while joining the resistance, she risks leading Ostarrichi forces to her home. If she leaves, then looking after Shen will fall to her cousin, who is already overworked caring for his frail grandmother.

As her society collapses into violence, Ashme must choose between her fellow Mesos, her family, and her values.
