NYPD hostage negotiator Gemma Capello is working undercover when she's taken captive by a paramilitary group threatening to destroy Grand Central Terminal in the latest thrilling NYPD Negotiators Novel-perfect for fans of James Patterson and David Baldacci.

NYPD detectives Gemma Capello and Sean Logan are cutting through Grand Central Terminal on their way to a nearby pub when all hell breaks loose. Masked men gun down police officers and round up a group of commuters-including Gemma and Logan-taking their cell phones and binding them hand and foot in zip ties. They are members of the paramilitary group known as Sinister 13, seeking the release of their imprisoned soldiers. Their leader wears a vest covered with C-4 plastic explosives, threatening to detonate it if their demands are not met.

To save the hostages, Gemma persuades their captors to allow her to negotiate with law enforcement on their behalf without revealing her identity. As she earns their trust, Logan plots to free himself to take on the gunmen. But time is running out. The abductors are growing more impatient and violent with every passing moment. With their NYPD colleagues on the outside, Gemma and Logan must use all their negotiation experience and tactical skills to prevent the situation from escalating into a bloodbath . . .
