Driven from their home by drought and disease, Tariq and his river tribe travel to the great capital city of Ethrial. But once they arrive, Tariq realises that they are still in grave danger - and time is running out! Tariq is a seer, and he's had a troubling vision of a tidal wave that will drown the whole city. But when Tariq warns of impending disaster, he's banished from the city. An ancient legend called The Saga of the Spiritstones might hold the key to preventing a disaster. Can Tariq and his new friends find a long-lost Spiritstone and use its powerful elemental magic to save Ethrial, and the people they love, from complete devastation?
