In this postapocalyptic fantasy, a sea of sand swallows everything but the past. In an endless sea of sand drifts the Mud Whale, a floating island city of clay and magic. In its chambers a small community clings to survival, cut off from its own history by the shadows of the past. The Mud Whale has finally reached the shores of Amonlogia, but it quickly becomes clear that Sir Rochalizo wasn't being entirely up-front when he said the people of the Mud Whale would all be welcome. His father the duke has placed harsh conditions on their citizenship, and they only have three days to agree…or face the consequences!
