Halloween is coming. “What are you going to be?” the children ask one another. Kimin says he will be his grandfather. “Going as an old man is not very scary,” they tease. What the children don’t know is that Kimin’s grandfather was a Korean mask dancer. And Kimin doesn’t know that the mask holds a secret for him.

With vibrant illustrations, Yangsook Choi joins Korean and American folk traditions in her story about a boy who finds a link to his grandfather, behind the mask.
