Nata de Cotton is a witch defined by one thing above all: an unquenchable craving for a candy called Willow. Her companion Silk — the fairy she once saved the world with — is approached by her sister Knit with alarming news: Queen Velvet has been behaving strangely. The cause turns out to be a burnt Willow. Silk moves to dispose of it. Cotton intervenes, grabs it, bites into it, and discovers it has been burned. She does not particularly care about the queen or the state of the kingdom. But someone burning Willows? That is a different matter entirely. Cotton and Silk go to stop them.
