A standalone story set in the New York Times-bestselling Greenwild universe! It's been ten years since the events of the original trilogy, and a new magical threat brings eleven-year-old Annika Marina to the far reaches of the frozen world as she fights for the future of blue magic.

Eleven-year-old Annika may be heir to the ocean-ruled kingdom of Iffenwild, but she’d much rather be sailing with her traveling theater troupe than learning how to be queen. But when her beloved uncle Max—the king—returns gravely injured from a secret mission to the Utter North, her world shifts in an instant.

Determined to find a long-lost cure, Annika journeys into the frozen North—a land of towering ice cliffs, frozen seas, and powerful ice magic. But the deeper she ventures, the clearer it becomes that something far darker is stirring. If Annika fails, it won’t just be her uncle’s life at stake—it will be the fate of the entire magical world.
