A serial killer is stalking national parks, and FBI Agent Kenzie Harper's team is scrambling to catch up.

When Kenzie catches the case of a young woman found dead in Rocky Mountain National Park, she gets more than she bargained for. The killer is transforming his victims, displaying them like portraits against the wild landscapes of the West. And his gallery is expanding.

As bodies surface across the parks, the investigation stretches Kenzie across hundreds of miles of unforgiving terrain. With her team on shaky ground and the case growing colder with every mile, a connection to a forgotten death finally exposes the obsession behind the kills.

But the Park Artist isn't done. Kenzie is running out of time before he adds another victim to his collection.

For fans of C.J. Box and Kendra Elliot, Frozen Divide is the fourth book in the Harper and Reese Thriller Series.
