Finished it!

Kill the Angel: A Novel (Caselli and Torre Series) - Sandrone Dazieri

I think this was better than the first book, but there were definitely some rambly moments that could have been dispensed with without losing anything. And there was still quite a bit of telling rather than showing, though this could be down to the translation from the Italian rather than lazy writing.

 

But I enjoyed it, and thanks to the enormous cliffhanger ending, I will definitely pick up the third book when it's published.
