The tale weaves together the real and the imaginary worlds of the main character, Nathan, with a magical otherworld.
When a shapeless shadow appears above the forest while he is out walking his dog, a series of horrifying events is set in motion. Nathan senses that something sinister is constantly watching him, its shape shifting from smoke in the sky, to animals and even a human being. He recognises that the menacing Creature is feeding on his own inner fears and that he must face them in order to destroy the entity before its power grows to the point that it will overwhelm him.
Characters are very well-drawn and the dialogue authentic. This gripping, atmospheric horror story for younger readers is a very good read, even for adults.
