Rayleigh Mann is just a regular kid, he has no idea though how special he is, for he is the son of The bogey man, ruler of Below London.
One year when he goes out trick or treating instead of just make believe ghouls and ghosts he meets a real monster.
One who tells him that his father Bogey is missing.
As his son, Rayleigh is the one they have turned to for help to find him.
He alone holds the key.
So he sets out to Below London with his uncle.
