I'm about halfway through it. Very good it is too. He's brought back Simon Darcourt (last seen trying to blow up the Dubh Ardrain Hydro) and expanded his serial killer attributes, sort of Dexter on Steroids. Lots of piss being taken out of fame-junkies, shock-journalists and the like. Very funny.
AFG is still my favourite of his book, but this one looks like being close. Definitely recommended.
