A father, who can't keep his promises, dies in a car accident. One year later, he returns as a snowman, who has the final chance to put things right with his son before he is gone forever.
Though the older snowmen at Little Snowman Stan's side tell him that snowmen must never move, or they will melt, every flake in Stan's snowy body wants to move. When he finally gets up the nerve to move, Stan finds a world of wonder and independence.
Readers follow the snowman Olaf, brought to life through the magic of Queen Elsa of Arendelle, as he accompanies Princess Anna to try to find Queen Elsa, Anna's sister, and bring her home.
