Query: Lost Credibility

It started off well. The main character is Isserley, who picks up male hitchhikers in the Scottish Highlands. I was interested, even though I don't know what icpathua is. But come page 135, I left the book. It lost its credibility there. If you've read it, then you'll know why. (DNF)
