NYPD Red by James Patterson
Every cop wants to be part of NYPD Red. It is the elite team in New York's police department, handling the cases involving the most important and high-profile individuals in the city. It's Detective Zach Jordan's dream job, but he's about to step into a nightmare. In the middle of a New York film festival, a maniac begins a very public and very brutal killing spree targeting Hollywood's biggest stars. Zach is assigned a new partner, Detective Kylie MacDonald, who is also his ex-girlfriend. But they'll need to put their history aside to have a chance of stopping this homicidal psychopath before he brings New York City to its knees.
