It took me two tries to read Artemis, I bounced off it hard only a chapter or two in the first time. Second time I finished it, but I definitely didn't care for the characters or the story anywhere near as much as his other two books - both of which I loved.
A person of taste, I see. I still have a couple of Rivers of London books left but I love the series. Have you read MJ-12 By Michael J. Martínez? If you liked The Fold and Rivers of London, it might be something for you. Anything else you could recommend?
