Whilst I have rated this book middle of the road, I actually found the overall story quite engaging. I thought the concept of Nazi experimentation rising 60+ years after World War II was a great way of blending mad science and zombie-like creations.
The characters were well defined, if not a bit too perfect (in the way things seemed to always work out for the main characters), and they all had reasonable back stories to support their place in the story.
I was, to be honest, a little disappointed in the simplicity of the ending, especially after all the chaos the team went through to that point. However, leaving an enticing opening for book two will most likely have me using a credit for a follow on listen.
Thanks to the author/narrator/publisher for providing me this audiobook in return for a honest review.
