Darkness Falling — David Niall Wilson

When Klaus Von Kroft brings his band to the mountain village of Rathburg to perform a concert, a generations old tapestry of blood and darkness draws about him like a shroud. Delving into the disappearance of his parents, Klaus finds himself entranced by Rosa, a sunset-haired woman of mystery and darkness, her companions, and the eerily perfect music they play. But Rosa is far more than mysterious. She has stolen the blood and souls of men on the mountain above Rathburg for centuries. As Klaus is drawn into her web of vengeance and blood, his friends are dragged along behind. Can he unravel the mystery of the mountain and overcome the call of blood…or will they all fall to Rosa's game of hunger and revenge?

The answer lies on the mountain, but there is little time…with Darkness Falling…
