Perennial New York Times bestseller Faye Kellerman ratchets up the tension a when a new generation done the blue.

Cynthia Decker became a cop against her father's wishes.  But police work is in her blood, and she's determined to make it on her own.  She begins to feel a nagging sense that she is being watched.  The feeling of dread escalates when she finds some personal effects have been crudely destroyed.  It'd a harrowing trip down a dark canyon road that substantiates Cindy's worst fear: for some unknown reason, someone fiendishly relentless is stalking her. Cindy begins to covertly probe her personal and professional lives for identity of the person who wants her frightened, harmed -or dead.  As her stalker grows bolder and more devious, Cindy finds her options limited and her friends and colleagues offbounds as the well-concealed rages and dark secrets of those surrounding her slowly come to light and threaten to pull a nightmare out of the shadows and in for the kill.
