December is Clemmie Merlyn's favourite month as it usually begins with birthday cake and gifts. But as she turns thirteen, it begins with a bang: Clemmie, and Clemmie alone amongst all witches, is full of magic. So full of magic she might not make it to the end of the month. As the snow spirals down, anxious Clemmie and the young hags will have to find some way to stop her exploding.
Because someone, or something, has chosen Clemmie and made her their One True Witch. But magic is meant to be shared and no-one can survive being filled to the brim with starry power. Can the Merlyn and Morgan covens finally take on the ancient twisted magic of their ancestors? And can they do it in time for Christmas?
