During this snowstorm, the true danger isn't the cold-it's the secrets people keep.

Olive Sterling and Jason Stewart expected Aegis's Christmas retreat in the Smoky Mountains to be a rare chance to breathe, reconnect, and enjoy a peaceful holiday away from the chaos of their high-risk world. Instead, they discover that even the most picturesque setting can conceal the darkest of intentions.

When Olive finds a teammate's body frozen in the snow, she instantly knows his death was no accident. As a brutal storm traps the team on the mountain with a killer in their midst, Olive and Jason must uncover the truth before the body count rises.

But when every footprint leads to more questions-and every teammate becomes a suspect-suspicion turns as lethal as the dropping temperatures. With trust eroding and fear closing in, Olive and Jason must decide who they can truly rely on-and who they can't.
