Ann and Lin have been busy learning how to be princesses. Clinton has been learning how to be a prince, as well as learning survival techniques and sword play. The first Celebration of the new year, The Heart of Snow, Winter Gathering and Competition, will be the perfect chance for the 3 siblings to relax. They are excited to have a break in the cold Winter, and to compete in the snow building competition! As they ponder what to build, they find themselves swirling into another world. However, they soon realize they are not alone.
