Another book which seems to have timed its publication to coincide with the run-up to Halloween, with some of the chapter titles such as All Tricks, No Treats sounding like they could be book titles themselves on the subject of All Hallows Eve.
Both the front cover and the use of intertextuality with the letter from Rayleigh's mother may indicate an emphasis on the "young" element of young adult reader, but when you take into consideration the central character Rayleigh (who is tasked with trying to find his father the Bogey Mann after a night out trick or treating doesn't go according to plan) as well as some of the turns of phrase - "for fright's sake" instead of the other FFS being one early example - and the twist of bad guys having to be forces for good there's enough edge to draw in adults/older young adults and keep them interested.
