Jessica and her cousin, along with their families, are on holiday at a ski resort in Idaho. When the two twelve year old take a detour from the snowshoe path they cross paths with ice beast. This is a chase story, one escape plan is put into action and fails, and that becomes a snowball effect through the story until the cousins are united with their fate.
Idaho ice beast fuels our fear of "what is out there and can it hurt us?" What would the reader do in that situation, well by chance the cousins find a cottage, a tree to climb, and remained generally unscathed by circumstances. Since this is a children's book, I suppose gruesome dismemberment is out of the question. These books do let kids tip toe into the kiddie pool of fear without making them afraid to drown. And adults can still read these for entertainment.
