Here's a very good review of Blood and Ashes from Linda Wilson at Reviewing the Evidence.
Reading it, I had to smile. Linda feels that Joe Hunter's introspection in this outing slowed things a tad, while other reviewers have pointed out the same thing as adding depth, humanity and character to Joe. It just proves that you can't please everyone all the time ;-)
...and thanks to Linda for a balanced and well-received review.
