Welcome to the Shifting Lands.

Silluka was born with only one arm and could never practice the exacting motions to summon the favor of the gods. Caught stealing, she is forced to test her powers or be branded an outcast. She fails, and loses citizenship to her village.

In a fit of desperation, Silluka tries to steal a badge of citizenship from a mysterious elder. But instead, Elder Quilqi shows Silluka a different path to gain the powers of the gods, aided by an octopus-like technological wizard who worships their own eldritch divinities. Time is short for training however, because a new island is speeding toward the coastal town, throwing deadly hurricanes and tidal waves before it, and threatening all who live there.

Only the gods and godlike storm warriors protect the village from destruction, but all of them fail when a mysterious creature bursts through the wall. It's only one forerunner for a species of terrifying turtlemen: fast, deadly, and ready to invade the larger island. The village must flee inland before the invasion, while Silluka is weighed down by her outcast status and her brother's failing abilities. To save herself, her family, and her village, Silluka must overcome stigma and self-doubt. She must learn the scope of the world outside her village. She must learn Physical Magic.
