It has been fifteen hundred years since the solar flare devastation of the Global Catastrophe. Due to the radioactivity in the harvesting fields, society dismisses its defective children as nothing more than flawed products of the malfunctioned seeds in the field.
But Lyratelle, a hyper-observant musical prodigy, believes these "defects" are intelligent, particularly her own sibling, the youngest child of her impervious mother. Abandoning her dream career, Lyratelle climbs the bureaucratic ladder to run the Defect Research Center, where she can safeguard the child.
With an underground team of women who share her uncertainties, Lyratelle unearths the Old History truth that womankind's survival actually hinges on the existence of these defects.
When General Sarah Love, the city's most powerful advocate against the defects, detects Lyratelle's sympathy toward the creatures, she threatens the life of Lyratelle's sibling.
Now Lyratelle's desperate attempt to save this child endangers everyone she loves--her team, her family, even the existence of the defects themselves.
