For years I've been following Peter Grant around as he manages his business with the Rivers of London and all other magical creatures in London. The comic series, for me, was the latest instalment and after some initial hesitation, I'm really glad I joined in on them.
While they are (so far as I can tell) not a major part of the continuing story of the books it is a great addition to them. This was involves a lot of Russians, and I admit there was some initial anxiety when the first page was in Russian, I couldn't understand a word of it and I believed I had accidentally ordered the wrong edition (my sister once ordered a German comic by mistake). Luckily, the rest was (mostly) in English!
I'm really looking forward to the rest of this series.
