Becky Masterman's FEAR THE DARKNESS is the masterful follow-up to the Edgar Award and CWA Gold Dagger finalist RAGE AGAINST THE DYING.

It’s hard to recognize the devil when his hand is on your shoulder. That’s because a psychopath is just a person before he becomes a headline...Psychopaths have preferences for Starbucks or Dunkin’ Donuts coffee, denim or linen, Dickens or...well, you get the point.

Ex-FBI agent Brigid Quinn has seen more than her share of psychopaths. She is ready to put all that behind her, building a new life in Tucson with a husband, friends, and some nice quiet work as a private investigator. Sure, she could still kill a man half her age, but she now gets her martial arts practice by teaching self-defense at a women's shelter.

But sometimes it isn't that simple. When her sister-in-law dies, Brigid take in her 17-year-old niece, Gemma Kate. There has always been something unsettling about Gemma-Kate, but family is family. Which is fine, until Gemma-Kate starts taking an unhealthy interest in dissecting the local wildlife.

Meanwhile, Brigid agrees to help a local couple by investigating the death of their son --- which also turns out not to be that simple. Her house isn't the sanctuary it used to be, and new dangers --- including murder --- seem to lurk everywhere. Brigid starts to wonder if there is anyone she can trust, or if the devil has simply moved closer to home.
