A golden fireball smashes into the Walters’ car during their summer vacation. Thirteen-year-old Cora survives without a scratch. Her brother, Nathan, spends two weeks in critical care and endures months of rehabilitation. Their parents are killed.
Nine years later, Cora works as a high-end call girl in Toronto and looks after Nathan, who suffers from schizophrenia, unaware of the supernatural mafia hunting the city for the one they call the Light. The mafia does not know what he looks like, nor how the powers of the Light will manifest, but their leader, Teresa, believes it is her only chance to destroy their progenitor before he wakes from his centuries-long sleep--and will do anything to find it.
When their search finally bears fruit, Cora’s daily struggle explodes into one for the siblings' very survival, perhaps requiring the ultimate sacrifice of all.
