When seven skeletons are unearthed along the Appalachian Trail, FBI Special Agent Margot Phalen thinks she already knows who put them there.

Margot knows how predators hunt. As the daughter of one of America’s most notorious serial killers, she’s turned her dark past into a weapon, becoming the Bureau’s expert at getting inside the minds of monsters.

Wyatt Holmes has been behind bars for a decade, convicted of hunting hikers like animals through the Tennessee wilderness. He claims wolves led him to his prey. Everyone thinks he’s insane and surely responsible for the newly discovered skeletons—until the bodies start telling a different story. The burial patterns are wrong. The timeline doesn’t fit.

And as Margot ventures deeper into the wilderness where Holmes once stalked hikers, she discovers a horrifying truth: someone else is out there.

This time, she isn’t the only one hunting—in fact, she’s become the target.
