Sometimes to be good, you have to be bad... When Rayleigh Mann sneaks out to go trick-or-treating on Halloween, he gets way more than he bargained for - in the form of a monster straight out of his nana's stories. The weirdest part? This monster tells Rayleigh that the father he never knew is actually the Bogey Mann. And there's more - Bogey is missing, and Rayleigh is the key to finding him. But to do so, Rayleigh must travel to Below-London, the magical underground world of monsters, where he'll embark on an adventure straight out of his wildest dreams - or perhaps his darkest nightmares.
