Atlantis has always been a myth—until now. Rising from the depths, its gleaming towers and forbidden technologies dazzle Scottie, Isla, Billie, Fallon, and Sabrina. But beneath the brilliance of its crystal cities, Atlantis conceals a darker truth: its power is fueled by ancient bargains, conspiracies, and a language capable of reshaping reality itself. As alliances shift and rival factions vie for control, the travelers from the Margins must navigate treachery at every turn. Billie uncovers Lemuria’s forgotten survivors hidden within the Atlantean court. Fallon hears whispers of Ragnarok echoing even here. Isla and Scottie stumble upon secrets the Atlanteans would kill to keep buried. And Sabrina finds herself drawn closer than ever to Antarctica’s role as the hinge of every lost world. But Atlantis is already doomed. The cataclysm that will shatter its empire is building in silence, a tidal wave of fate none can escape. When it comes, not even the First Language may save them. Echoes of Atlantis is the penultimate chapter of the Echoes Saga , weaving together myth, conspiracy, and ancient power in a tale of grandeur and collapse. For every empire that rises, there must come a fall—and this time, the echoes may drown all worlds with it.
