This is the usual fast paced retired special forces adventure with the addition of zombies and Nazis. Of course the zombies are both human and animal which adds some twists and lots of flying lead, but nothing really compelling. The plot is so over the top that it hard to take the characters seriously. The crazy Nazi scientists has been done to death and this is not any more believable.
The book was narrated quite well by Maxwell Zener who dealt with the large variety of characters and accents pretty well.
I was given this free review copy audiobook at my request and have voluntarily left this review.
