Almost read by everyone on my flist or on their to read list. I got it last year and I was finally in the mood for it.
Same amazing awe discovering the universe Aaronovitch created as when I first read Liz Williams' Chen series. He has created an alternate London very close to the real thing, the reader can almost walk besides Peter and follow him pursuing leads, meetings deities and doing magic things.
It's entertaining, it has action, magic and a little pinch of wow that makes this a special reading treat.
Not grand literature but good, solid and entertaining literature that built a whole alternative world just below the surface of ours.
I have the second book waiting to be read later this summer.
