The Season Fairies make the weather, each kind having its own specialty. Only full-fledged fairies have this ability. Sugar is an apprentice Snow Fairy. She and her friends have had all of the training and now need to find magical “Twinkles.” Unfortunately, none of these fairies know what a Twinkle is. However, they do find a human girl, Saga, who can see them when others can’t. Saga prefers a quiet and orderly life, becomes the rather unwilling helper to these noisy, lively, little fairies.
