About This Book
The salty breeze carries the distant cry of seagulls and the rustle of palm leaves on Island X. Scarlet feels the heartbeat of the island’s animals pulsing through her fingertips, while Jem builds tree houses high above the sandy shore. But when the fierce Pirate Captain Wallace Hammerstein-Jones and the King’s Men arrive, the island’s secrets—and its treasures—are suddenly in danger.
