A hidden chamber beneath a forgotten lighthouse. Six teens awakened by ancient power. A lost continent rising from history to claim them. When sixteen-year-old James Carter stumbles upon a glowing tile beneath the Roosevelt Island lighthouse, he unleashes a surge of ancient magic that ripples through New York City. The blast awakens extraordinary abilities in five other teens-psychic echoes, shadows that move, flames that ignite, wounds that heal, and the power to bend time itself. Drawn together by a force none of them understand, the six uncover a secret buried for ten thousand years: the lost realm of Aeonis and the drowned city of Atlantis once relied on seven mystical keys to protect the world from an ancient threat. Now one of those keys-the Tide Key-has chosen James as its new bearer. But their awakening has stirred something else. Beneath the water, the Devourer, a monstrous shadow born from Atlantis's final night, begins to rise. Its whisper summons the Saltborn-creatures of bone, coral, and darkness-hunting the new heirs before they can learn the truth of their powers. As visions of Atlantis's fall haunt them, James and the others must unite, master their abilities, and face a destiny that could save the world... or drown it. Epic, cinematic, and emotionally charged, The Tide Key launches the Sunken Throne Saga-an adventure of ancient magic, found family, and the storm that changes everything.
