A wildlife biologist's shocking death leads to chilling discoveries in Christine Carbo's haunting and compelling new crime novel set in the wilds of Glacier National Park.

Glacier National Park police officer Monty Harris knows that each summer at least one person - be it a reckless, arrogant climber or a distracted hiker - will meet tragedy in the park. But Paul "Wolfie" Sedgewick's fatal fall from the sheer cliffs near Going-to-the-Sun Road is incomprehensible. Wolfie was an experienced and highly regarded wildlife biologist who knew all too well the perils that Glacier's treacherous terrain presents - and how to avoid them.

The case, so close to home, has frayed park employee emotions. Yet calm and methodical lead investigator Monty senses in his gut that something isn't right. So when whispers of irresponsibility or suicide emerge, tarnishing Wolfie's reputation, Monty dedicates himself to uncovering the truth - for the sake of the man's family and to satisfy his own persistent sense of unease.

Monty discovers that Wolfie's zealous studies of Glacier's mysterious, embattled wolverine population, so vital to park ecology, had met resistance, both local and federal. To muddy the waters further, a wilderness facility for rehabilitating troubled teens - one that Monty's older brother attended - may have a disturbing connection to the case. As Monty delves further into an investigation that goes deeper than he ever imagined, he wrestles with the demons of his past, which lead back to harsh betrayals he thought he'd buried long ago.

And then a second body is found.
