Movieland / Lee Goldberg.

Enhanced descriptions from Syndetics:

Malibu Creek State Park is a beautiful locale for campers, tourists, hikers, and Hollywood. For Detective Eve Ronin, it's a backdrop for murder in a riveting thriller by #1 New York Times bestselling author Lee Goldberg.

For decades Malibu Creek State Park was the spectacular natural setting where Hollywood fantasies were made. But when a female camper is gunned down, it becomes a real-life killing ground. Los Angeles County Sheriff's Department homicide detectives Eve Ronin and Duncan Pavone are assigned the case...which Duncan fears is the latest in a series of sniper attacks that began long before Eve came to Lost Hills.

Seven victims over fourteen months...and top officials still refuse to see a connection. Eve and Duncan are stonewalled, threatened, and ordered to keep quiet. But Eve won't back down. She's no stranger to intimidation or corruption--she's had a target on her back from day one at Lost Hills station.

Despite finding no evidentiary links between the shootings, Eve and Duncan follow their instincts into the shadows of Malibu Creek, where it's not enough to expose the secrets and break the conspiracy of silence. They also have to make it out alive.
