The Sensation by Amanda Bridgeman

A series of brutal murders has the homicide division of San Francisco's Hub 9 working overtime. But as the bodies mount, they begin to question whether the attacks are random or somehow connected. When one of their own falls victim, Detective Salvi Brentt and her team join forces with the narcotics and cyber divisions to track down those responsible. They soon discover that a volatile new drug-tech experience, involving black market neural implants, has hit the streets, causing the epidemic of violence and missing persons. With the clock ticking and the death toll rising, Salvi must go deep undercover in the seedy Sensation club scene to find out who is behind the deadly drug-tech. But in the secretive playgrounds of the rich and powerful, some will stop at nothing to protect their empire... AVAILABLE FROM AMAZON OR YOUR FAVORITE BOOKSELLER
