The Wolf in the Clouds

In this "edge-of-the-chair thriller" (San Francisco Chronicle), six people are trapped in an avalanche of horror—and one of them is an armed psychopath gone berserk.
An isolated cabin high on a stormy Colorado mountain that becomes snowbound in a raging blizzard. A homicidal maniac with superb mountaineering skills and sharpshooting aim with a rifle. Two local forest rangers unaware of what they’re walking into—and the trio of college kids they have come to rescue. As the freezing temperatures drop even lower, and the snow on the mountain above them accumulates, the danger and the tension pick up nightmare speed.
