The Darkest Evening of the Year Koontz, Dean

Amy Redwing runs a Golden Retriever rescue in Southern California, pulling dogs from shelters and placing them in homes. When she responds to a late-night call about an abandoned golden, she finds herself pulled into something far darker than animal cruelty — a web of violence and obsession stretching back years. Koontz builds dread quietly here, wrapping genuine menace around domestic scenes and rescue work. The dog at the center of the story becomes both witness and catalyst as Amy's past collides with a present threat she didn't see coming. This is Koontz leaning into psychological suspense rather than supernatural horror, though the tension runs just as deep. The golden retrievers provide emotional ballast against some genuinely unsettling human behavior. For fans of everyday evil done well, or anyone who's ever loved a dog enough to risk everything.
