***** Who is watching Nell Masters? Nell Masters is certain she’s being watched. Every day she feels a prickling unease on her morning commute, silent phone calls echo in her office, and an extravagant bouquet arrives at her doorstep – no card, no clue.

But Nell has reason to look over her shoulder. Because Nell has a secret…

Fourteen years ago, Nell witnessed a young woman get into a stranger’s car. When that woman was later found murdered, Nell became obsessed with finding the killer – a fixation that led her down a dangerous path. But has the hunter become the hunted? Or is there something even more deadly at play?
