An isolated hotel. A blizzard. Guests that can't stay on their feet. Hotel Hell is about to live up to its name.

Seven couples head up into the Swiss mountains for gourmet food and world-class skiing unaware that a freak change in the weather is about to unleash old secrets and ignite smoldering anger.
As sickness spreads through the guests, Mercy Watts' nursing skills are put to the test. The symptoms are similar but not the same. Something isn't right. She can tell, but she can't diagnose. She has no equipment and no way to reach any.
When a healthy guest is attacked and nearly killed, Mercy knows it can't be random, but it has to be. No one has connections to the victim, or do they?
Is anyone who they seem to be? There's no time to spare and no one to turn to. The vacation Mercy didn't want to take is going to take more out of her than she ever expected.
