A road trip. A milestone birthday. A grueling Ironman. A mountain retreat where nothing is as it seems.

Private Investigator Liz Adams and her husband, Brad, set out with friends on a meticulously planned adventure to Colorado. Along for the ride are their truth-sniffing Labrador, Duke, and Jenny’s adorable mutt, Snooper.

The adventure kicks off with a nostalgic visit to Dollywood where the first unsettling mystery unfolds.

And then . . . a phone call that changes everything.

The cheerful mood evaporates. Unanswered questions loom, and grief rolls in like a dense mountain fog.

When they reach the sprawling rental meant for birthday cake and victory toasts, the search for answers begins. Amid the stark red rock formations of the Garden of the Gods, Duke follows scents no one else can detect.

In the thin mountain air, evil lurks. And this time, danger may be closer than Liz thinks.
