Caught in the grip of ruthless Asian gangs, the Chinatowns of New York City and Toronto are the North American headquarters for a worldwide criminal network specializing in extortion, drugs, immigrant smuggling, and murder. Detective Cisco Sanchez personifies the city he protects. Brash and cocky, he's also one of the best investigators in an elite division of the NYPD. But when his fiancee is gunned down in a Toronto restaurant by elements of a feared Vietnamese gang known as Born To Kill, Cisco's next assignment is extremely dangerous--and extremely personal. Teamed with his partner Brian McKenna, Cisco has to battle departmental rivalries, vicious street killers, and heavyweight financiers as corrupt as they are connected to follow the investigation around the globe and all the way to the top of Hong Kong's organized crime world.
