Sam McGrath has always rejected his father's love of mountaineering. Now, at a low point in his life, he sees the chance of escape. Fiercely attracted to a young Canadian doctor he meets in a stormbound airport, he decides on impulse to follow her as she goes to be expedition doctor for an attempt on Everest.

Two men driven by different demons, and a woman with her own history . . .
