Five hundred years ago the world shattered, banishing the gods from the Sister Continents and stealing the memories of the mortal peoples in an event known as the Great Forgetting. In seventeen days the stars will align, and a religious cabal will summon the gods back to the realms of men. In the northern tundra priests search the Steaming Lakes, a place tormented by the Wakened Dead. Deep in the mountains, demonic shadows assail priests at a holy shrine. In the south, the clans know something foul is afoot, and dispatch warriors to seek answers, but instead they find horrors.

A young priestess named Eliles stands in the heart of this conspiracy; on her shoulders rest decisions which could prevent a holy war or demonic genocide. Through lies, manipulation, and murder, everyone is on a seventeen day march to fulfill or defy prophecy; the world will end or begin anew, come the Eve of Snows.
