Dawn of the Demontide (Witchfinder, Bk. 1)

The first in a terrifying trilogy, read on if you dare:

Jake could now see the demon fully. Its body was a mass of steely sinew, its arms roped with muscle. Six fingers sprouted from its hands, each ending in lethal talons. The thing did not possess a nose; instead a large hole, bubbling with green mucus, occupied the middle of its face. Mr. Pinch's tongue flickered between his teeth and slurped across his fat lips. He was hungry.

When a violent storm rages around the little village of Hobarron's Hollow, a young boy is sacrificed 'for the greater good'. His blood is used to seal a mystical doorway and prevent an apocalyptic disaster known only as the Demontide.

Twenty-five years later, another boy, Jake Harker, is about to be drawn into the nightmare of the Demontide. Witches and their demon familiars stalk his every move, and his dreams are plagued by visions of a 17th Century figure known only as the Witchfinder. When his father is abducted, Jake must face the terrible secrets kept by those closest to him and a shocking truth that will change his life forever . . .
