There’s something out there in the darkness.
By morning, bones lie in the snow, picked clean.

Zach knows the moods of the mountains – his mother taught him before she was gone. His father and the other men on the ski weekend think they know better though.

Drinking and boasting, they laugh in the face of the icy conditions.

But Zach understands what danger looks like. Can he survive the wilderness, and all the monsters within it?
