There is a place where the creatures of nightmares exist. They have been spoken of and written about through time, myths and legends passed from generation to generation, their stories finding a nesting place in the minds of children. Sam Love is about to find them... and they are about to find him... and a jolly fat man in a red suit is watching on with interest. 35 years ago shadows drift across a midsummer festival in Hollow's End and a little girl disappears... 35 years later, Sam and his family move to a new life in the country village of Hollow's End. Initially the only place he feels comfortable is in a treehouse in an ancient oak tree outside his bedroom window. But nightmares start and Sam gets his first glimpse of the dangerous world he's about to be drawn into. He finds a comforting ear in his new neighbour, an old farmer called Bob, and the two begin to forge a friendship - but it guides him down less travelled woodland paths and into a world between night and day.
