With boat tours off the coast of Alaska shut down for the winter, tour guide Stacie Calder is joining the dedicated team at the Juneau Wildlife World, a wild animal sanctuary. Along with Sasha, her husky companion, she’s prepared to spend the long season in the scenic park. But not everyone is so chipper about the newcomers—least of all, Stacie’s new manager, Oliver Brownling. He constantly gives Stacie a hard time, specifically because she brought Sasha along with her. That is, he did until his mauled body is found in a remote part of the sanctuary containing wolves.

When it becomes clear that a human was responsible for the brutal murder, all eyes are on Stacie. Encouraged by her friend, Officer Liam Amaruq of the Alaskan State Troopers, Stacie is resolved to find the murderer but knows that her investigation will be difficult with the long suspect list she’s made. Did the sanctuary director plot to get rid of Oliver? Or maybe it was one of Oliver's coworkers, upset over a missed promotion? Stacie wonders about some of the newer employees, especially since Oliver’s personality made it easy to make enemies.

With the weather worsening, Stacie and Sasha are forced to stay at the sanctuary with the wolves—and her colleagues. As the storm gets worse, it’s clear that this killer has a taste for blood and may strike again. Will Stacie be able to find the murderer, or will the hunter become the hunted?
