A number of bodies are discovered on the United States border with Mexico, each carved with a bizarre symbol: a hummingbird. Detective Cecilia Garza of the Mexican intelligence agency recognizes the image: it is the calling card of a killer called Chuparosa. Garza has pursued this killer for years, yet knows little about him, except that hes heading to New York City-along with the rest of the world. Its United Nations Week in Manhattan, and Jeremy Fisk, an integral member of the NYPD Intelligence Division, cant let his grief over a devastating loss keep him from safeguarding the city and the world's most powerful leaders. Complicating matters is the startling news of a mass murder on the beach in nearby Rockaway-and the arrival of a beautiful and assertive Mexican detective determined to do things her way.
