This was a solid story. I enjoyed it quite a bit. However, I thought it plodded along in some places - although never slowly enough to lose my interest. The biggest gripe I have with it is that I didn't understand how the protag knew the map to the underworld etc. yet no one else did. His role sounded akin to mayor, not High Priest (granted, I do not know fully the scope of his title). I also hoped for a slightly darker ending, but not everything can be a downer I suppose! But besides that, I really liked this story.
The language was good and never came across as clumsy, but I wouldn't go so far as to say it was great: again, nothing really stood out for me.
Great reading, great intro and outro.
