Don't go outside.

Max is trapped.

A freak snowstorm has him sealed in his uncle's mountain cabin, along with his brother Mark and sister Teresa. But Uncle Shoe is missing, and no one's coming to rescue them. Should they take their chances and hike down the mountain to safety?

Max doesn't think so, especially not since he found those huge tracks in the snow. Then there's that inhuman howling coming from the woods.

Now barricaded behind the cabin door, Max thinks he knows what it might be. He's found some old reports that the Abominable Snowman, the yeti, was sighted there fifty years earlier. Has it returned?

The kids aren't taking any chances. They've boarded up the cabin, because as much as they want to get out . . .

Something else wants in.
