This was another fantastic installment in the Black London series, just as dark and gritty as the previous books this one is instead set mainly in LA. I thought the change of place would take away from the grim and foreboding atmosphere as the Black in London is a character almost as much as Pete and Jack. I am happy to report that I was wrong, LA had a feeling of its own, not with the same impact as London, which has had three other books to build it up, but it was interesting to see a new place for Jack and Pete to wreak havoc in.
Devil's Business was told entirely from Jack's POV, which was fantastic, Jack is one of my favourite UF heroes (I use the word hero lightly here!) he is deliciously fucked up and completely different from any other male characters I have read. But in this book we saw him be the reluctant savior and see Jack willing to sacrifice anything to save Pete was unexpectedly sweet as you know he wouldn't bother for anyone else.
As in all the other books in this series the writing was engaging and coarsley beautiful and the plot was fast moving, bleak and threatened the apocalypse, all of which kept me riveted to the page. It also gave hints of things to come, it seems like Jack and Pete are in the centre of something big and world ending and I can't wait to see what that is!
