Holly and Ivy are a new pair of matching, colourful Christmas socks. They are very fond of each other. One day, something unexpected and strange happens, and Holly finds that Ivy is suddenly missing. Holly feels rather sad, but luckily, she will be reunited with Ivy very soon – on Christmas Day itself! A sweet, festive story that introduces young children to the concepts of temporary loss and the possibility of helping others through second-hand clothing charity shops.
