The Raven Flies at Night

Ravens are bringers of bad luck and harbingers of the supernatural...just ask the people of Mountainview.
Hundreds of them invade the sleepy mountain town, and bring with them death, destruction, and two high-ranking officials from hell.
When the town's church comes under attack, demon hunters Johann Gunter and Robert Durling run toward the destruction to save the priest inside.
In the ensuing battle, Johann and Robert discover who the person is that is responsible for conjuring the demons, but they still have one surprise coming.
