From publisher blurb:
At the edge of the world lies Ustrea - a range of mountains and deep forests. of deadly predators, and of a secret darker than the night.
Ustrea isn't directly on the edge of the world. but the fact remains that no one has ever been known to travel beyond it. To this end, no one knows if there is more to this world. Those who live in the outposts at the edge of the mountain range and forest will tell you that while some may enter no one ever returns, and so only the foolish would dare.
Every century the world of Ustrea dies in a blaze of brilliant foliage in colors that disappear almost as soon as this season begins. The chill then creeps in. finger-biting. the temperatures plummeting far below that of a regular winter. It begins to snow, and does not stop for a full year. Somewhere. deep in the forest. something wakes.
The wilderness waited this long century for people to serve it. For people who could match its power step for step. blow for blow. To serve the land and the divinity that lies within it. There are rumors of such people living deep in the country, never seen by travelers, and never leaving any evidence of their existence.
Until now.
Bodies have been found near each of the Outposts. mutilated and left for dead by unknown assailants. Nobody seems to have seen what happened. but the truth is simple something dangerous lives in these forests, and it is getting bold.
