Many of the names in the story are plucked from the whos-who of occultists including the house at the centre of the story. Living in 666 Crowley Avenue should have been a sign that Seances mightn't go well. Add in a weakening of the walls between the worlds by the Hadron Collider, one boy and his dog, humourous footnotes (many of which are actually quite informative) and you get this gem of a book. Samuel Johnson is a great character, trying to cope with being smart, his dad leaving home (what happens to his dad's car is probably what many kids would like to happen to a car their dad appears to love more than them) and he faces the real problems of a kid with imagination faced with problems that adults in his life don't want to be real. I enjoyed the read and would recommend it.
