Fourteen fairies have escaped into our world, all different, and all capable of causing great harm--and it is up to an eight-year-old girl named Violet and a Pixie Tricker, a fairy called Sprite-of-the-Green-Petals-from-the-Whispering-Woods, to trick them and send them back to their own world.

When Max and his sister Rose go to visit their grandmother's lakeside vacation home, they soon discover that their nightly sleeps bring them to a timelocked place with kids from all different eras, united by their love of the lake--and Max begins to wonder if they can help him to find his missing mother.
