More of a 3.5 stars. 
 So far so good. It was nice to see a bit of Cain and Abel and know what I was heading into, but what really kept me reading was the frame, if not the internal stories as much. 
 I think I prefer all the "simple" stories that have a lot more interesting things going on in the frames best. Very tongue-in-cheek. 
 So far, it isn't brilliant or anything, but I will stay the course to see where it eventually leads. I can't dislike a story about stories, after all, I am a big fan of the style, be it The Arabian Nights or Sandman. I hope there's more arc and less episodic things going on, though.
