I read Nele Neuhaus’s Bad Wolf in early 2014 and reviewed it on Goodreads. I enjoyed it but (apparently!) found there to be too many characters as I had trouble keeping track of everyone. I wondered at the time if Neuhaus really needed to introduce quite as many players (names and details) though later realised it was the 6th in the series*, so guess regular readers had time to familiarise themselves with the many characters.
I noted at the time however one of the German author’s previous novels, Snow White Must Die, had received great accolades.
