I received my copy of Maze of the Blue Medusa today. Like most books Zak's involved with, this is a piece of art. The book is mainly system agnostic and doesn't have to-be-read-aloud sections. I don't think I'll use this anytime soon, but I am looking forward to have a group of pc's enter the painting. You should expect to hear more about the exploits in the maze in the future.
