When seventeen-year-old Liora Vale discovers that her late grandfather's mysterious silver compass has awakened, she follows an ancient stone pathway revealed by the retreating ocean and uncovers a truth hidden for thousands of years. Guided by the legendary sea guardian Aravyn, Liora learns that the Sleeping Dragons beneath the ocean are awakening as an ancient force threatens the balance of the world. As she journeys across forgotten islands, uncovers the fate of her missing grandfather, and embraces her destiny as the heir to the ancient explorers who once protected the seas, Liora must unite dragons and humans before old enemies and forgotten secrets plunge the oceans into chaos. Along the way, she discovers that the greatest mystery is not why the dragons disappeared-but why they chose to return now.
