A quest through a thousand worlds. An aeons-old foe. Not even the gods can help. It''s killing them, too.

IN THE YEARS BEFORE THE CORRUPTION CAME, Murrin Kentle lived in a world where the largest island could be walked across in a day, and humans traded and fished in bladeships made from the bones of the gigantic and bizarre sea monsters patrolling its stormy, bottomless oceans. As a truthkeep of the Brotherhood of the First Mind, it's been his duty to fight the decay of knowledge with religious fervour. A fervour he has increasingly struggled to maintain.

Before the Corruption came, Sheehan hahe Seeheeli was a carefree countess of the Shi'iin. Amphibious and fiercely matriarchal, her people have maintained an uneasy coexistence with the human scholars dominating the islands. Then an emissary of the gods brings news of an impending catastrophe. Now, she and Murrin must embark on a desperate voyage in the hope of salvation, although both the subject of their search and the path they must take remain stubbornly obscure.

Before the Corruption came, a wild young man named Coll grew up in a desert town, consumed by rage over what was done to his mother. His thirst for retribution will set in motion a train of events not even the gods could fully have foretold.

NOW THE CORRUPTION IS HERE, and nothing in Murrin's world, nor any of the worlds of the Sundered Realm, will ever be the same.
