Two shots ring out from a rooftop. When the smoke clears, Detective Chalice is down and her rookie partner is dead. She's sustained a traumatic head injury that has left her with a compromised memory and suffering from seizures.

Hurt, raw, and angry, Chalice is set on retribution. Joined by her former partner's brother, Detective Yanagisawa, she will let nothing stand in her way as she pursues the shooter through the dark underworlds of American and Japanese organized crime.

But will Chalice's obsession with vengeance stand in the way of her catching a mysterious psychopath who's been preying on the young women of New York City? With a young child of her own to keep safe, Chalice must see justice served on all fronts before it's too late.
