The Unkindness of Ravens

Andrew is a homeless war veteran who has been experiencing terrifying flashbacks of his time in the army that contain visions of imposing raven-like creatures. The flashbacks are so intimidating that Andrew has developed a phobia of ravens and as a result he travels to a retreat in the Scottish Highlands to come to terms with his past and his fears. However he soon discovers that this is easier said than done, as this move will bring him face to face with a supernatural force known only as the Raven Warrior, and he will end up fighting for his sanity and his life.
