Assistant DA Alexandra Cooper returns in the new breakneck thriller by the New York Times bestselling author of Death Angel who once again captures the essence of New York City--its glamour, its history, its possibilities, and its endless capacity for darkness. Grand Central Station is hiding more than just an underground train system. When the body of a young woman is found in the tower suite of the Waldorf Astoria, Assistant DA Alex Cooper and Detective Mike Chapman find themselves hunting for a killer whose only signature is a carefully drawn symbol carved into his victims' bodies, a symbol that bears a striking resemblance to train tracks. After a second body is discovered in a terminal alleyway, attention shifts to the iconic transportation hub and the potential for a bigger attack. With the President of the United States set to arrive for a United Nations meeting, Alex and Mike must contend with Grand Central's expansive underground tunnels and century-old dark secrets--as well as their own changing relationship--to find a killer who's cutting a deadly path straight to the heart of the city.

New York City. Central Park. For thousands of residents and tourists who fill it every day, it's an enormous urban sanctuary. For one killer it's the perfect hunting ground. A young girl has been found dead in the Ramble, a secluded section of the park made up of winding paths, dense woods, and dead ends. Is she the first victim of a psychopath? Or a clue to other missing women in years past whose remains have never been found? For the answer, Assistant DA Alexandra Cooper and Detective Mike Chapman follow a twisting trail of evidence that takes them deep into the city's dark history--and deeper into the mind of killer whose work has only just begun.

As she follows his trail deep into the desert, she runs face-first into a staggering history of betrayal and death: the wreckage of a hidden past. Carl Perreira was not the man she thought she knew - nor was he anything she could have imagined. Her journey will teach her as much about herself as it does about Carl. And as she plunges closer to his fleeing shadow, she will find herself fighting not only for the truth, but for her life.

As a Senator's daughter and top investigator in the homicide division of the Metropolitan Police Department, Fiona maneuvers between two vastly different worlds, moving quickly from opulent State galas to gritty crime scenes.
