OK, I have finished The Dark Wheel.
It was OK as stories go. I didn't like that it jumps forward with no explanation that it has, you are left to figure that out. The main characters seemed to progress far too easily, and it came close at times to Mary Sue characters. I felt the ending was rushed, the story could have been much longer, but it was edited down to fit, and the ending inserted to conform to a word count.
I did like that it clearly has been written as the game was being developed.
The biggest shame is that Rob Holdstock isn't here to reply to our comments.
