This is a fast paced page turner that drew me in from the very beginning. Gemma Capello is an NYPD hostage negotiator, from a close Italian family, most of them fellow NYPD officers. Even when she is off duty, she jumps into action to save lives. The call that interrupts a family picnic will lead Gemma on a dangerous mission that will threaten her life and her career. Filled with descriptive history of New York City, and meticulously researched police proceedures, it also leaves you wanting to know more about Gemma and her family. Her dad Tony, an NYPD Chief of special operations, and her brothers: Alex, an internal affairs "rat", Joe, in the gangs division, Mark, a patrol sergeant, And Matteo, the lone sibling who joined the FDNY. I'm sure subsequent books will feature more of the family! But back to this first book: Gemma has to use all of her skills to stop the hostage taker from his crazed mission.. She will need the help of her best friend Frankie, Her brother Alex, and her knowledge of the little Italy neighborhood.to stop the madman. There's also a little teaser of a former romantic interest who factors into the ending. This is one of those books that keeps you up late at night, reading as fast as you can because you don't want to put it down, but you also don't want to miss anything. An excellent start to what promisses to be a fantastic series! .I received an e-book from NetGalley in return for an unbiased review.
