Winter Blue is a fairy-child. She leads parallel lives in two worlds – the world of humans, and another, secret, wondrous world – Magic-Land. As an ordinary thirteen-year-old girl she attends school every day, does her homework, and spends time with her friends, none of whom know her secret. Each night, she turns into a fairy and flies to Magic-Land where she meets other fairies, dwarflings, wonder-horses, fixit moles, pink babies, and other magic beings. One day, a series of strange events starts taking place -events that disrupt the tranquil lives of all Magic-Land dwellers. A wonder-horse falls into the human world, dangerous pits are torn in the ground, and the fairies’ gems of power begin to vanish, one after another… Winter and her friends, other fairy-children, set out to investigate the mystery. They experience a series of adventures, face numerous dangers, and expose a conspiracy that threatens the very existence of Magic-Land. The plot takes place simultaneously in both realms, sweeping readers into a fantastic, gripping and mysterious story.
