This is book 5 in of the seven Pelbar series by Williams. I have read this series about six times. It is intriguing. If anyone has read this series I'd love to discuss it with you. I'm beginning to believe that I am the only one in the world who has actually read it.
Set in far post-nuclear North America. Stel must enter the very capital of an enemy people's lands to rescue his daughter from slavers.
