Kate Cornell knows two things for certain: The worst monsters are human. And she's not the hero people think she is. When a massive blizzard isolates her Colorado mountain town from the outside world, Kate discovers something else in the storm that turns her sanctuary into a nightmare. As the snow keeps falling and the body count rises. The threat stalking Lake City isn't human at all. Kate's past trauma taught her to face monsters when everyone else freezes. But this time, she's not alone. With a small group of friends trapped with her, surviving means confronting something far worse than the memories that haunt her, or the reporter determined to expose her secrets. And she'll have to protect the people she cares about while keeping her own dark history buried. The darkness hunting them didn't come from her past.
