Probably Ghostwater or Dreadgod by Will Wight. I love that man’s work.

I like the idea of tolken, but I think he’s actually a shitty writer. He should have left over 50% of his work in the editing room floor. So many extra details that just take away from the reading experience. I feel like he actually wanted to write a dnd module for his world rather than a novel. It reads like an encyclopedia.
