A wordless story. The pictures have the hazy softness of air in snow. A little boy rushes out into the wintry day to build a snowman, which comes alive in his dreams that night. The boy invites him home and in return is taken on a flight high above the countryside.

It is a very hot summer in Stermont, and Alexander and his friends are at Camp Gloamy in the mountains, but even here there are monsters--specifically zombie snowmen called snombies who want to freeze the young monster-hunters.

Desmond and Andres face a snowman that was built by a schoolmate but seems to have a mind of its own, as well as a snowball-throwing bully.
