It's a distant time of horse-drawn carriages and cheerful jingling sleds. It's also the year of the Christmas Full Moon; a rare moon which is rumored to bring about the most wonderful gifts! The 'Gift' however arrives in the rather frightening form of a ghost. With his bent top hat and torn black tuxedo, he looks like someone who had just risen from the grave; for this is a 'Testing Moon Trogg!' Here the eleven year old Azelda realizes that she's been chosen for the Trogg's mysterious test; she's to uncover the dark secret that her 'witchy' neighbor Viola holds inside. Azelda soon learns that people and things are not always as they seem. Indeed, Viola isn't so mean after all; for like a dark cloud that covers the warmth of the sun, she suffers from the painful secret of a broken heart. With her newly found understanding, Azelda heals Viola's heart with a loving kindness that she thought that she would never find again. The two become friends, as a most lovely and meaningful Christmas is had.
