When secrets kill, she gets even.

A murdered mom, a weird ritual, and her childhood apartment up in blazes—that night still haunts Helen Carver. She always watched her uncle, safe on the sidelines, as he chased empty leads trying to figure out what happened. Now grown with a daughter of her own, she's tired of watching and ready to help...right as he goes missing.
As she retraces his steps, Helen finds a strange hidden society. Its glowing beings attack her with impossible speed, magic spells, and archaic weapons. Everybody has secrets. Anyone could be a threat. But one thing becomes crystal clear: The mystery around her mother's murder now threatens her kid.
Nobody touches Helen's little girl.
