The best cure for a depression? Saving the world of course! Helen is betrothed to a man who raped her, she is the oddity in her village, and whispers of sacrificing her to appease the darkening sun isn't exactly lightening up her mood. When a prophecy of eternal darkness is revealed to her, revealing why the sun is darkening, taking away the precious rays of energy that makes the Solung survive the eternal winters of their lands, Helen makes the choice to leave her moral-ridden village and her predetermined life behind, to stop the world from becoming as dark as her mind has been. But in the darkness of night Helen's path will collide with a creature of the night; Ten, a soldier from the dark territories of the north. Unbeknownst to both, and despite the bloodied history between the two people they represent, they must find a path together to change the world forever. Or else, all will be lost in darkness.
