Currently working my way through the second entry in the series, Moon Over Soho, and it's a wonderfully modern bit of anglo-fantasy police procedural fare. It suitably enough reminds me of Absalom but lacking the violent edge and instead being a bit more light hearted and comical. Enjoying it very much so far and glad i've got the rest of the series ahead.
You should also check out the comic series from Titan Comics that runs in conjunction with the novels with lovely artwork from Lee Sullivan (Dr Who, Transformers, Death's Head & Judge Dredd)
