Cassidy Vinewood needs a vacation from her fast-paced New York lifestyle. Desperately. When an advertisement for the idyllic Lone Tree Lodge appears on her computer screen, she clicks into action. Cassidy's excited to read near the warm glow of the fireplace and banter with the lodge's handsome owner.

As the resort town prepares for the blizzard of the year, an old tale of a mountain creature prowling the endless white landscape sends the indefinitely snowed-in guests into a flurry of excitement. When one of the patrons experiences a tragic snowshoeing accident, Cassidy knows something more sinister is afoot. With temperatures and trust between guests plummeting, Cassidy must discover the murderer before it's too late.
